No location with IOS 16/17

Hello, since approx. 1 month the presence detection on the iPhone with IOS 16 (in the meantime IOS 17) in the Home Assistant suddenly no longer works. The HA Mobile App also correctly displays all locations in the course, they are just apparently not transmitted to HA. My iPhone with IOS 15… Is displayed correctly in HA.
I was hoping that the update to IOS 17 would solve the problem, but it doesn’t.

Are there any solutions for this?

Thanks a lot
