Auto Time to Initial Display for React Navigation is always 15 seconds

[krystofwoldrich]

Description

On some Android devices the auto instrumentation for time to initial display results in heartbeat timeout and the TTID span is always 15 seconds.

To avoid this bug you can you the manual instrumentation <Sentry.TimeToInitialDisplay record={true} />

• Example of this behaviour from a user report Android initial load screen time is way above then it should be #3847

Moving the discussion to this thread, as you asked in the issue, I was using only real devices for those tests, and my navigators are structured like this:

Stack Navigator (root)
   └─ Tab Navigator
      └─ Stack Navigator

Tbh I didn't know we also could define the TimeToInitialDisplay the same way you can with the TimeToFullDisplay, I was relying only on auto instrumentation for that. I'll add it and see if it solves the issue.
