Mixpanel Events Not Working in Telegram WebView for Flutter App

kapa.ai We’ve noticed that users who open our Flutter Web app inside Telegram (i.e. via the Telegram in-app browser/WebView) don’t generate any Mixpanel events. Everything works fine when opening the app in Safari or Chrome. Has anyone else encountered the same issue with Mixpanel silently failing inside Telegram WebView?

I'm sorry, but the knowledge sources do not contain any specific information about Mixpanel failing or behaving differently inside the Telegram in-app browser or WebView, nor do they mention known issues with Flutter Web apps in this context.However, the documentation does highlight that client-side tracking (including Flutter Web) can be unreliable due to factors like ad-blockers, privacy settings, or network restrictions, which may be more aggressive in certain in-app browsers or WebViews. It is also recommended to use a proxy to reduce the likelihood of events being blocked by such mechanisms, but there is no explicit mention of Telegram's WebView specifically causing issues with Mixpanel event tracking Choosing the Right Method Tracking Via Proxy.If you suspect events are being blocked or not sent, enabling debug mode in the Flutter SDK may help you diagnose if events are being attempted and if any errors are returned Debug Mode.In summary, while the documentation covers general troubleshooting and known issues with client-side tracking, it does not specifically address the Telegram WebView scenario.
kapa.ai is still learning and improving, please let me know how I did by reacting below.
