TypeScript Ampli Wrapper not compiling

Hi,Using npm dependencies @amplitude/ampli v1.31.2 and @amplitude/analytics-browser v1.9.1, the generated wrapper does not compile with our current TypeScript version 4.8.4. Documentation mentions a version requirement > 2.1 Also, event names containing single quotes also generate non-compiling code (our event names are written in natural french language). Single quotes seem to be handled properly on property names though.

Measuring Lness

I have a product whose target use is N days a week, but I’m not finding a straightforward way to measure Lness. I first tried to solve for this using custom retention brackets, but that wouldn’t give me what I need as they’re tied to specific days (retention on D1-D3, or retention D4-7, etc.).Is there a way to measure Lness on Amplitude?

Cloning a branch

Does anyone here knows if is possible to clone a Branch for a tracking plan version from one project to another?The easiest example would be: from devs working in Dev environment, where they already created a branch, is it possible that, once we already are happy with the outcome of our changes and have the branch ready in Dev, to “clone” this branch into the Prod environment, to avoid doing all that manual work again?

Amplitude - Intercom integration throttling, internal errors; attributes not showing up on Intercom

Over the last day, I got 55.2k failed events not sent to Intercom due to Destination Throttling, Internal Errors and Invalid Requests. Specifically Throttling and Internal errors nature is not clear to me. What should I do to fix these issues and pass data without such failures?In addition, the user attributes from Amplitude I've selected to send to Intercom don't appear there. The events are recorded fine (with the exception of issues I listed above). What is the reason? Will the attributes get created automatically similar to events, or do I need to manually create the custom attributes I expect to receive on Intercom first?

Tracking new Groups

Hi,I want to track new groups added (in the “Accounts” addon) in a chart.So far I select “New Users” and “performed by” any of a specific group (see screenshot).I think this will give my any group that contains any new user. But acuually I just want any new group counted.Is there a good way of doing that?

Uploaded user ID cohort reduced by half

I imported a cohort from a CSV file with x k rows of user IDs (email addresses). Amplitude is now showing an amount of significantly less users (cut by a couple thousand) in “population over time”. Why doesn’t this compute to the original row number in the CSV file? Where is the exclusion of user IDs happening? Thanks.

User Property [Carrier] None vs Unknown

When querying about user property : Carrier. I get values “None” and “Unknown”What does a value of “Unknown” mean vs “None”. Does None mean the device does not have SIM card? Does Unknown mean there is a SIM card but the Carrier is not a well known carrier?

Why am I seeing "(none)" values in my chart results?

Hello everyone!When grouping your events by an event or user property, you may have noticed that some of your results have been sorted into a group titled '(none)'.'(none)' in Amplitude represents a null value, but sometimes when you use Microscope and check on a user’s profile, you see that there is a user property value in the top panel. Why is the user being counted under ‘(none)’ when the have a value in their profile? Let’s walk through why this happens.Amplitude is an event based platform, and all charts and cohorts query at the event level. This means that we are querying for event and user property values that were present at the time of the event. Our colleague John also recently posted a video explaining this concept: This is different behavior from what you see at the top of a user’s profile (in the User Lookup section), where properties in the upper panel represent the most current user properties. In other words, they reflect the property values that were most recently upd

Flagsmith Integration not working

Hi, I’ve integrated my Flagsmith with Amplitude but I couldn’t see any events received. I’ve talked to Flagsmith support and they confirmed the events were sent.I can’t see them neither on the web dashboard nor on the Dashboard API responses.

Hi!We will buy new plan, but now we don’t want to exceed limit and blocked some events.If we unblock them and exceed limit, then when we buy new plan can we see all events, which was over limit historically?

Fetching usage time for a user from Amplitude API

We're looking at surfacing to the user their time spent in app and noticed Amplitude already by default tracks this, but getting a successful response from the dashboard API (User Activity) has not been fruitful (usage_time is currently returning null from this endpoint even though usage time shows up fine in the dashboard, and it’s unclear why).There might also be a better endpoint for what we want as I'm sure fetching past activity for a user is pretty expensive - we only want the usage_time property for the user. Is there a lighter-weight, non rate-limited endpoint we could use?

How do you get up to speed on your data taxonomy?FAQ

Maybe you aren’t familiar with what each event is for and how to use it in charts. Here are some quick tips to get up to speed fast: Use Amplitude’s event explorer Chrome Plugin to see what events are firing in Amplitude as you interact with your product live. Go to a user profile on the user lookup page and scroll down to the User Properties section. Here you’ll see the various user properties your team tracks for each user. Search for events in Amplitude’s Data (previously Govern) section to see all the events and properties your team tracks. You can see event meta data in Data including descriptions, tags, owners, etc. For more information as you get up and running, explore our getting started resources and the Getting Started with Amplitude Data course in our Academy.

How do you determine how many times on average songs are played by users within a given duration?

Hi guys, Considering the AmpliTunes example where there is a “Play Song or Video” event with a “Content_ID” property. I’m interested to find the average amount of times a song is played per duration (hourly, daily, weekly, etc. dropdown). Is there an advanced formula to count the unique content_id’s and then divide them by the number of users to somehow get a number like on average, each song is played 1.2 times per user? I started on something like this, but got completely lost. Would appreciate any help! Thanks!https://analytics.amplitude.com/demo/chart/new/uwvn0gb

client upload time is not device local time

Hi, https://amplitude.com/blog/dont-trust-client-datahttps://help.amplitude.com/hc/en-us/articles/229313067#Raw-Data-FieldsAs I understand via above links.Device Time can be incorrect and “Server Received Time - Client Upload Time” can be assumed as approximate difference between device time and real time.Thus, Event Time(Client Event Time + Server Received Time - Client Upload Time) is used on Dashboard.But, in my case, I used React Native SDK, and changed device(android real device) time. and install my app, and send data. Client Event Time is based on device time, but, Client Upload Time is based on real time. (There is no offline status)Then, event is misrepresented on chart by device local time not real time.How can I see chart based real time?

Count total single events by unique property in a time period per user

Hey,I’m trying to work out if I can understand how many times a single specific event has been fired per user, but only count it once per user based on a unique property. We have a Course Completed event which has property of Course ID, which determines which course a user has completed.A user can complete a course multiple times and can also complete different courses.I’d like a report that shows me the number of times a cohort of users has triggered the Course Completed event in a month, but only count the course completed once based on the Course ID.Following is an example of individual users and then the required output:User A - completed course ID ABCDE = 2 times / completed course ID FGHIJ = 1 time / completed course ID KLMNO = 1 time User B - completed course ID ABCDE = 10 times / completed course ID FGHIJ = 6 times / completed course ID KLMNO = 5 times User C - completed course ID ABCDE = 10 times / completed course ID FGHIJ = 1 time / completed course ID KLMNO = 0 times User D

Distribution of propert values in increasing intervals

hi, I want to plot properties of an event in a histogram with increasing intervals.The properties span a huge range (file sizes), but most of them are smaller. I still want to group the bigger ones. E.g. from 0-1 MB, 1-10, 10-100, 100-1000, 1000-10000 etc.Is this somehow possible automatically, or do I have to create many events with filters?

Use an event property id in place of user_id

Hello, I’m wondering if there’s any way to use a string sent as an event property in place of the user_id for the event. Use-case: In the product there are events where a user takes action on another users posts e.g. like, comments, etc. In the ‘like sent’ event for example there is an event property called ‘target_user_id’ which has the user_id of the user receiving the like. I’m wondering if there is a way to use this field in a new event so that the result would measure when a user receives a like (instead of gives a like) and could be used in subsequent engagement and retention analysis. Thank you!

How are devices assigned to users?

Our stats show a lot of users with many device IDs. Like 20+. And many Merged IDs.How can I figute out based on what they were merged? It feels unnatural and I want to avoid us having an error in our tracking, missleading the numbers.

Change Amplitude "User ID" for old users

We plan to change the logic of the Amplitude user property "User ID" setup. Previously, we used to pass the value from our backend system there, and now we will start passing the firebase user id. We are planning to rewrite the value of this user property to firebase.user_id for old users (i.e. for all those who will have the "User ID" value before the logic is changed). Can our analytics "break" from changing the values for old users?
