Re-enable foreground service with special notification channel, upgrade ACRA version
Summary:
Insert back the foreground service notification (and permission), complying with Play Store
Also, avoid non-stop request of trip data that simply fails to download, giving rise to less notifications on devices that run Android < 12.
Test Plan: Check nothing is broken
