This app ID is listed twice in my account. Maybe this is the cause of the missing entitlement?

Have you got this issue fixed? I am facing with this issue right now. My additional capabilities does not have "User Assigned Device Name".

CoreLocation startMonitoringForRegion and startMonitoringSignificantLocationChanges no longer restart terminated app in iOS 15. I can confirm with my own app and other similar apps. This makes my app unreliable. If you have this issue, please submit a bug report to Apple. If we have more bug reports with the same category, Apple might pay more attention to it. Please note that it is still not fixed in iOS 15.2 beta 3.
