Ive seen this happen a few times lately, but it was occurring on an app that I was actively developing. It was perplexing because I knew the app wasn’t actually polling for location. It didn’t even have background location capabilities; I could attach a debugger and confirm.
Only by resetting the device could I clear the system location alarm. I can eventually reproduce the issue again after a few force quits of the app.
It’s a UI bug in iOS. The app was unlikely doing anything malicious.
I had it with an application I uninstalled (Paycor Scheduling) still supposedly claiming it was grabbing location even though the .app was fully removed from my device. I also had to restart it to clear that notification.
