iOS Geofence no launching app properly. Why?

Hello all!

Right now developing application that should be starting by crossing geofence. Right now have strange problem. The application launching when some other application keeping CoreLocation active and gathering data on iOS 15, on iOS 13 all is working with delay, but working. The geofenge regions started for monitoring, there are presented icon on top bar.

What is missed by me in this case? Is there working example?
