>>Geolocation on iPhone is not updating and displays incorrectly

Hello! I’m having an issue with geolocation on my iPhone: my location isn’t updating and continues to display incorrectly.

At the moment, all my subscriptions have expired, and I have left my Family Sharing group, but the problem persists.

Could you please tell me what might be causing this, and what else I can do to get it working correctly again?

Thanks in advance for your help!<<

Did you check, that no restrictions have been set up on your iPhone?

I guess you have already tried to force restart the iPhone after the latest iOS update?

...

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button.
4. When the Apple logo appears, release the side button.

If this does not help, try to erase it and set it up as a new device, to rule out any defective data from the backup:

...

1. Go to Settings.
2. Tap General.
3. Tap Transfer or Reset [device].
4. Tap Erase All Content and Settings.
5. Tap Continue.
6. Choose to keep or delete your eSIM. If you erase your eSIM, you need to contact your carrier to reactivate your cellular plan.
7. Enter your device passcode.
8. Wait for your backup to finish. 
9. Enter your Apple Account password.
10. Tap the done button ✔️ on your keyboard.
11. Wait for your device to reset.
12. When the process is complete, the Hello screen appears.
