Hi iet8

Try a clean uninstall and reinstallation.

Clean uninstall:

1. Uninstall the app.
2. Go to a file manager (apps like ES file manager; File Commander or File Manager).
3. Set “Show hidden files” to ON (i.e. so that hidden files are shown).
4. On both SD Card and Internal memory find the folder named .here-maps and remove/delete it.
5. On both SD Card and Internal memory check if there is still com.here.app.maps folder present (/Android/data/com.here.app.maps/)
6. If it is present, remove/delete it on both SD Card and Internal memory
7. Restart the phone
8. Install the app again
