Using Amplitude

hello. I´m trying to set up a cohort where I will see only the users with no e-mail address in their UserID. Is my definition wrong? (still see the users with their e-mails in this cohort) 

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? 

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.

How to sync amplitude cohorts to hubpsot without losing user properties.In other terms, the current amplitude cohort sync contains all required information, however hubspot is only saving the email. any work arounds to save the remaining properties from amplitude in HubSpot?

Hey, anyone knows how to calculate page level metrics (keeping constant Page URL dimension).What I need to to build a table with:Page URL > Page viewed event > Engaged event > Page engagement rateThe page engagement rate is calculated as follows: (number of engaged events / number of page viewed events) * 100. However, I'm unsure how to calculate this in Amplitude. I’ve attempted various methods to implement this formula, but for some reason, the results don't align with the engaged/page viewed values when I use the calculator.Again the metric must be page level, not session or user level.Many thanks to anyone that can help

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.

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!

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.

Hi team. I have been trying to create event analytics and unable to copy/save the dashboard as I get the error failed to save chart. Could someone look into it provide an update on how to fix this issue? It has been happening for the last 24 hours.
