Thanks for your feedback. I just reported the bug.

I have the same issue with our app. I'm testing with iOS 15.2 beta right now and the problem still exists. Usually you can turn off location services and turn it back on and it works again for a few hours (which of course is not the solution). (I have the same problem with Location Events since iOS 15, I suspect this is related).

I've been testing with iOS 15.3 beta 1 for the last couple of days. So far, everything works as expected. Looks like it got fixed
