The pic belo may give some idea of what maybe happening.


Also, check if you have stored offline Maps on your device.
Offline maps in Apple Maps are stored on your device's local storage and are independent of the app itself. Reinstalling the app won't affect these downloaded maps.
Here's a breakdown of why:
- Apple Maps downloads specific areas you choose for offline use.
- This downloaded data is stored on your device's memory.
- Reinstalling the app only affects the app files, not your device's data storage where the maps reside.
However, it's always a good practice to double-check your downloaded maps after reinstalling any app. You can find them under the Offline Maps section within the Apple Maps app itself.
