Why can I connect to Test Lab, but the session_start event is not triggered on iOS or Android?

This typically indicates a missing or misconfigured SDK initialization. Please verify the following:

  • Is the Insider SDK initialization code present in the app?

  • Is the SDK initialized as soon as the app launches (e.g., in AppDelegate for iOS or Application.onCreate() for Android)?

Correct SDK initialization is required for lifecycle events such as session_start to be triggered.
