Hi there,
I'm using Bluetooth-LE, and I can see that apps might crash in RELEASE under TestFlight,
while they work well in DEBUG.
This happened never on older iOS versions, so I still try to find the real reason for crashing.
What I think is that the bluetooth-le flag not only controls the download from AppStore,
but maybe also might cause internal crash's, if not defined.
I use bluetooth, with UIBackgroundModes "location", "bluetooth-cetral" and "audio" background modes,
which worked well before (and still does in DEBUG), but now shows the typical permission crashes, all on modern phones and iPads with iOS13.4.1.
My configuration: Rx10.3.3, XCode 11.4.1, iOS13.4.1.
Maybe I need to define bluetooth-le in the UIRequiredDeviceCapabilities, or does that doesn't make any difference in apps behaviour ?
