Same here. It happens multiple times when our app wakes up in the background due to crossing a geofence (didEnterRegion / didExitRegion). iOS version 15.5 Any updates on this?

After trial and error, I figured out what the issue was. The deployment target of the Location Push Service Extension was set automatically to the latest iOS version (16.4 at the time of this post), but the device where it was built had a previous version of iOS. I fixed it by changing the General > Deployment Info on the Location Push Service Extension Target to iOS 15.0 (minimum iOS requirement for this feature).

Still same issue here. Data stored in group UserDefaults is not cleared.
