I have the following issue:

I’m getting a lot of reports like this saying the app is hanging but I don’t think actually is hanging, it’s just the app going to the background and being cleaned up by the OS.

Screenshot 2023-02-14 at 7 45 41 AM

Steps to reproduce: Unknown, came in via sentry.

Actual result: Seeing false issues.

Expected result: Should only report hangs when it actually hangs

Could it be that these notifications are not posted adequately on a Flutter app, @marandaneto?

I don’t think Flutter interferes with that, the notifications are an OS feature.
