Description
I have app that runs in background and plays audio. on firebase 11.8.1, it runs for 8+ hrs without crash.
With 11.9, it crashes in the background in an hour and half. even with no foreground activity (screen off).
I tested this 3 times (debug build, release build and testflight build on real device running ios 18.3.1) with both versions of firebase, and got consistent results - 11.8.1 runs over 8 hours. 11.9 crashes in an hour and half roughly.
Nothing in my code has changed, only change was firebase version.
I also see no crashlytics crashes either (I know crashlytics crashes are being properly shown/processed - i have a test button with fatalError() to test that).
I guess if some background task is run longer than 30 seconds - app shall be terminated in the background?
i see warnings in debug logs on debug build - APMAnalyticsMeasurementBackgroundTask taking longer than 30 seconds
Reproducing the issue
App that has background audio permissions, plays audio in the background.
Run the app in the background. at some point it is terminated.
