Page title is showing as (none) even though the event is sent

Hello, I’m facing this problem where my Amplitude dashboard still contains empty page titles even though I am seeing the events being sent on the web app. For context, I’m using NextJS. The page title is generated using generateMetadatahttps://nextjs.org/docs/app/api-reference/functions/generate-metadata I am not able to figure out why we are still receiving events with empty page titles. Screenshot of Amplitude Data Table

Revenue event marked as both Verified and Unverified

I am sending Revenue events from my NodeJS backend using the SDK.As per the documentation, all the revenue events from backend should be marked as Unverified.But some of the events are marked as Verified as well. Some events are also getting duplicated with both Verified and Unverified status. How can I make all of the events to come under one category?

Stitching Sessions Across Mobile, Web, and Server-side

Hello everyone,I'm currently trying to figure out how to stitch sessions across sources. Here's the scenario: a user starts a session on our mobile app and is then redirected via an external link to a web flow that also uses our web SDK. I want the web event to be part of the same session that started on the mobile app.Would sending the session ID as a parameter in the redirect link and reusing it to manually set the web session ID accomplish this? Or is there a better way to achieve this? Additionally, some events might be triggered from our backend server using the Amplitude API, which could also set both the user and session IDs.Any suggestions or insights on this would be greatly appreciated!

Multi-tenancy: How to set user properties before tracking events? Alternatives without user property?

Hi everyone, I am working on a multi-tenant application setup where users can access:customer1.example.com for Customer 1's tenant customer2.example.com for Customer 2's tenant And so onIn my code, I have a tenant variable that is sent to Amplitude, as shown below:useEffect(() => { if (!userId || !tenant) { return; } amplitude.init(AMPLITUDE_ID, { userId }); const identifyEvent = new amplitude.Identify(); identifyEvent.setOnce('tenant', tenant); amplitude.identify(identifyEvent);}, [userId, tenant]); I am using @amplitude/analytics-browser version ^2.11.2. This works well for our custom events when triggered (like page load or button clicks) as the tenant property is included.However, we also have Amplitude's autocapture enabled, which captures two initial events on page load that lack the tenant property:[Amplitude] Start Session - missing tenant [Amplitude] Page Viewed - missing tenant Page Load View - includes both tenant and userId See the screenshot for more detailWhen

Can you migrate data from Mixpanel to Amplitude?

You can send data from Mixpanel through our backfill process using the Batch API. Some additional instrumentation best practices to remember:  Multi-platform products: Different taxonomy = different projects, same taxonomy = same project If different platforms have same taxonomies, then send to the same project (allows for cross-platform analysis) Create test projects: Have a test project for every production project Instrumentation limits: 2000 event types, 2000 event properties, and 1000 user properties Character limits: 1024 for all values, 10,000 for arrays if using append/ prepend operations Data values: ISO-8601 format (YYYY-MM-DD hh:mm:ss)  Sensitive data: We recommend NOT sending any PII/ non-compliant with privacy regulation data to Amplitude.  Comment here if you hit any roadblocks. The team and your peers are here to help!

Using GTM Template + Autotrack w/ Segment

Hi, we are currently using the Google Tag Manager Template to autotrack page views, form submits, and clicks on our marketing website. We are using Segment in the product once a user signs up to track various product events. We also have Segment on the website, but it’s not integrated with Amplitude there. I’d like to know how we can ensure that Amplitude’s GTM tag uses the Segment anonymousId, so that we can ensure that both Segment + Amplitude utilize the same anonymousId to ensure proper identity resolution once a user logs in or signs up.

Reset Amplitude Session in Backend

Hello! I need to reset the Amplitude session, device ID, and user ID when a user logs out. I'm essentially looking for a way to perform an amplitude.reset() operation on the backend (in Ruby). Is this possible?

Sending parameters on content vs non content screens

Hi Amplitude team and community,Our team’s React Native-based app serves domestic and international news to users worldwideWe're just getting some basic taxonomy and tracking elements organizedIt's important to us that content screens (a news story, an opinion piece, etc.) send additional parameters and values, like author, publish date, etc.However, we're interested in making sure those content-specific parameters/values (author, publish date, etc.) DO NOT send on non-content pages (like a section front, settings screen or other screen that doesn't have those specifics).Does Amplitude (or do other community members) have any recommendations for or against this practice? And do you recommend any best methods to go about this?

Offline-first mobile app Autocapture feature

Hello,We're developping an offline-first android app and are considering Amplitude for our Analytics. I saw on the community that the SDK will store up to 1000 events when offline, and the recommended way to bypass this limit is to store the event offline ourselves and to send it to the Batch API or the HTTP API when the app is connected to the internet :  What about the autocapture feature ? I guess there is no way to use this feature when we store the events offline ourselves and that we can only store the events we create manually ? Or is there a way to disable the 1000 events limit in the configuration of the SDK ?

Safari on macOS Fails to Load Vue.js Site When Amplitude Browser SDK 2 is Integrated”

We have a Vue.js website that uses Amplitude as a primary analytics tool. Everything works well in general but we have some problems in Safari on MacOS.Once we add Amplitude module into the project, our website doesn't load on Safari. If we remove Amplitude module, it starts loading again.In chrome, it always works well, with&without Amplitude.We are using Browser SDK 2 and we tried both from npm registry(@amplitude/analytics-browser@^2.11.8) and from cdn(v2.10.0) directly. None of them worked for us.We are using Vue.js v3.3.4 with Vite v5.2.8.Can you please help us to figure out what the problem is?

Multiple users on same device

We have a mobile app on devices, sort of a kiosk situation, that is shared by many different users throughout the day which causes a problem with tracking.To be clear, all users of the app are required to log in. There are no anonymous uses of the app.After the first user logs in and sends events, when another person logs in on that device, all event tracking is sent as the first user. It isn’t until the app is force closed and restarted that events appear as the new user.This is highly problematic as all the data for a dozen users is only tied to one user, causing inaccurate reporting.We are calling Amplitude.setUserId and Amplitude.identify, setting the userId before each tracking call. We have also tried using Amplitude.reset(), but nothing has worked.Can anyone help? Thank you.

What is the reason for "none" being recorded in the event property?

Hello,What is the reason for "none" being recorded in the event property? In our app, we have set it up so that all events are logged with predefined values, and if the value is unknown to the app, it is recorded as 'N/A'. However, in the actual Amplitude data, more than half of the values are recorded as "none."I am curious about the cases where "none" is recorded.

Performance Issue After Adding Amplitude Tracking Snippet

Hi everyone,I’m experiencing a performance issue after adding the Amplitude tracking snippet to my website. Specifically, after implementing the snippet as described in the documentation, my site’s performance has noticeably decreased.I added<script src="https://cdn.amplitude.com/script/<apikey>.js"></script> <script>try {window.amplitude.add(window.sessionReplay.plugin({sampleRate: 1}));window.amplitude.init('<apikey>', {"fetchRemoteConfig": true,"autocapture": true});} catch(eAmplitude) {console.log('Amplitude not installed: ', eAmplitude);}</script> For example, when I click a button to open a Bootstrap modal popup, it now takes a few seconds to respond. However, when I remove the Amplitude tracking code, the modal opens smoothly without any delay.Has anyone else encountered this issue? If so, do you have any suggestions on how to resolve it or optimize performance while keeping Amplitude tracking enabled?Thank you in advance for your help!

Inaccurate new users

Ever since we attached user IDs to users, our daily new users increased significantly. We are only storing events for our ios users and the new users count is surpassing our app download count which doesn’t make sense.

I want to see all user IDs that have accessed a specific page.

Hi. I was wondering if there is a way to see how many user IDs have accessed a page called, for example, abc.com/a, and it would be nice to see the total number of user IDs.Currently, the way I've tried to look at this is by setting [events] under [segmentation] to abc.com/a lookup events, and [filter by] under [segmentation by] to user ID.  Additionally, I'm a free plan user. Once I did this, nothing was found for the User Id. I'm looking for help.
