Troubleshooting
App Will Not Start
If OMN4 does not reach the main map screen, start with the safest checks first.
Try These Steps
- close the app fully and open it again
- restart the device
- check whether the app offers a reset or recovery prompt after repeated failed starts
- sign in again if the app asks for your account details after recovery
Important Warning For Mobile
Avoid uninstalling the app as a first step on iPhone, iPad, or Android. Reinstalling can remove downloaded maps from the device.
If Startup Problems Continue
- make a note of the app version from About if you can still reach it
- note the platform and device model
- contact support with a short description of what you see before the app stops
If the app resets and then opens normally, give sync time to restore supported cloud data and then re-download any offline maps you need.
