If you are on Android and recently updated to 3.3.3, it is possible that you had a custom crosshair color selected in the previous version. We are aware of an issue with this on Android only, that causes the app to crash when you open any map.
To fix this:
- Open Avenza Maps
- Go to Settings > Display > Crosshair Color
- Select the Default color option
Once the Default is set, the maps should open correctly now. Once the map is opening correctly, you can change the crosshair color again This will be fixed in our next release (3.4).
If you are still having problems, please contact us for further help.
