Does Amplitude SDK affect app download time?

Hello :)I have one question related to the effect of Amplitude SDK on the app-size. We have currently enabled Amplitude over Segment, but thinking to integrate Amplitude SDK directly. So, I am wondering if integrating the Amplitude SDK will affect app performance and increase app download time?Thank you. Best, Mateja

Segmentation chart user property missing

Background of chart:Using the Segmentation chart, I have a basic event that only triggers past the stage a user has authenticated and is identified. When I group by a user property (user_type), there is about 20-30% of users grouped as `none`.The problemWhen I download those users to CSV and see their user property in question, it’s set to a value and not actually `none` at all. (When I use the user look up tool, they’re also set.) Why does the chart show as none?Does anyone have any advice on how to trouble shoot and increase confidence in this data?Extra detailsScreenshots attached (CSV download of “none” users), chart results and query criteria. It’s consistent if I group by under the event on the user property or the global chart grouped by option.Screenshots.

Reporting on Time to Value in Amplitude

Hi Guys! I’m fairly new to Amplitude and have been asked to try to find our TTV (time to value) for a specific event in Amplitude. This would be mapping from when the user first encounters our product to the specific event firing. I have tried using a Funnel report with the time to conversion from Any Event to the Form Submission event but my manager isn’t sure if it is correct. Does anyone have any suggestions for other methods to report to Time to Value?Thank you!

Unique page views in Amplitude differs from Segment data

We have a Segment - Amplitude events pipeline.Recently I found that the unique number of page views in Segment differs from Amplitude. Segment data:I take all page views and GROUP BY COALESCE(UserId, AnonymousId) Amplitude:Simply a segmentation by `Views` (Page event) + Unique users. The difference is about 20%, so I’m trying to figure out which value is correct, or how is the unique number is calculated?

Incorrect date format for processed_time field from the Export API

Is anyone else seeing incorrectly formatted timestamps from the Export API? This is causing an error for a script I have that calls that API.The issue I’m seeing is that events roughly with a processed_time value that’s between 2022:05:27 01:02:50.047099 and 2022:05:27 11:28:48.569078 do not have that field in ISO-8601 format. An example of the format I would expect is 2022-05-27T00:27:49.773Z.From the Export API documentation, it’s stated that that field should be an “ISO-8601 formatted timestamp.” which means the year, month, and day should be separated by a hyphen. Any help from the Amplitude support team would be much appreciated. API docs for response data, copied here:{ "server_received_time": UTC ISO-8601 formatted timestamp, "app": int, "device_carrier": string, "$schema":int, "city": string, "user_id": string, "uuid": UUID, "event_time": UTC ISO-8601 formatted timestamp, "platform": string, "os_version": string, "amplitude_id": long, "processed_time": UTC ISO-8601 formatted ti

Amplitude web vs Snowflake Data

Hello. I'm comparing amplitude data we get in snowflake vs what we see in amplitude web funnel analysis and we have more count of events in Snowflake. Why is this and is it possible to get a perfect match to amplitude web? I'm holding session id constant and doing the same in snowflake SQL.

Calculate the retention from D0

I really need help because I'm starting to pull my hair out on this supposedly "simple" subject. I would like to be able to analyze the retention at D1, D3, D7 and D30. For now, I just want to know which users are coming back after creating an account. To do this, I have set up a custom event called "Successful sign up" which, as the name suggests, is triggered when the user creates an account. (I can't leave the default "New user" event because my application is made so that you have to create an account to be considered as a user. It is possible to open the app and see the content without having an account. Therefore, if I leave it as is, I end up with a very low retention)For the return event, I left the amplitude one, namely "Any active event". In fact:- in D0 I have 100% with 115 users.- in D1 I have 51% with 47 users.- in D2 I have 43,3% with 29 users- in D3 I have 31,9% with 15 users- in D4 I have 24% with 6 users...- in D5 I have 28,6% with 4 users ....As you can see, all the n

I am wondering how many days it will take before somebody converts on my website.

My assumption is that it takes several days before somebody converts on my website, how can I get the insight how many sessions I need for this? And how long does this take as in total days before they convert?

Find intersection amongst Users

Hi All, In my application I will be exposing users to multiple Experiments. we want to figure out number of times a user gets exposed to more than 1 experiment, and when they do we want to figure out the different experiments that they were exposed to. As an extension we also might want to bring time/session into picture. Ex- If a user gets exposed to more than one experiment within the same session or within a fixed time intervalI(lets say 1 hour), we need to monitor that. Do we have a standard way to accomplish this?

Subscriptions with a trial period: how to properly track conversions?

Hi Everyone!Do some of you have a subscription business model on mobile apps? Do you have a trial period for your subscriptions?We have trouble properly tracking this, I mean the conversion after the trial period or the cancellation if the user cancels before the end of the trial period.We use Google Play store and Apple App Store APIs.I would be very interested by any feedbacks on successful implementations 🙏🙏🙏Have a great day!

How do I send event Properties?

I use the following code in my Flutter app / Dart: Amplitude.getInstance().setUserId(userID, startNewSession: false); Amplitude.getInstance().logEvent(actionName, eventProperties: { 'pageName': pageName } );When I check the Event Stream, I see the pageName property as an Event Property.But when I attempt to create a chart to GroupBy page Name for a given actionName...I don’t have that option.

what's an example or tutorial of Amplitude with Flutter (custom actions)

I am building a Flutter app and would like to instrument it with a Custom Action so I can send events to Amplitude.However, I haven’t seen an example of how to use the flutter-amplitude pub.dev package with a Flutter app in this way.I searched here and Stack overflow and haven’t been able to find an example.

Not receiving any User ID data in User Properties

Hi there,We’re facing an issue where we’re not receiving any [Amplitude] User ID at all under User Properties. Other things, such as Carrier, City, Country, Device family, Device type, DMA, IP address, Language, Library, OS, Platform, Region, Start version and Version are working normally.Our app is built with Flutter and we’ve tested the Flutter plugin and User ID is set correctly. This explains how we set it:abstract class AmplitudeAnalysis { static final _amplitudeAnalysis = Amplitude.getInstance(); static Future<void> init(String apiKey) async => _amplitudeAnalysis.init(apiKey); static Future<void> setUserId(String userId) async => _amplitudeAnalysis.setUserId(userId, startNewSession: true);And this explains where we set it (when the app fetches user profile after user is authenticated)// Set user ID to analitycs unawaited(AppsFlyer.init(profile.uuid)); unawaited(AmplitudeAnalysis.setUserId(profile.uuid));Can someone help us out?

Problem with user being identified after opting out for analytics

Hi, I have a question regarding an issue we noticed with user being identified (user personal data, such us email, name, surname and phone number are visible under the userId) after he/she chooses to be opted out for analytics (data collection), as per the GDPR regulation the user has to have a possibility to choose to be opted in or opted out for analytics.Once user registers and chooses to be opted out for analytics, the anonymousId is generated and the user is not identified. If users decides to opt in for analytics, the userId is generated and user is identified (we have visibility on his personal data, such us email, name, surname and phone number...). After some time, if user chooses to be opted out, the user personal data is still visible, I am guessing that is because the amplitudeIds and deviceIds are being merged under one userId. is there a workaround, for the user personal data to be hidden or deleted after the users chooses to be opted out for data collection?
