osmand does not load maps and suggests a fresh install
will this wipe out my favourites/photos/audio and video?
can I uninstall and reinstall the app without losing my data?
if not, how do I save my stuff?
without previously removing the app: will it ask to just install updates if I install ‘over’ the existing version?
This is the forum for OpenStreetMap-the-database, not OSMand-an-app. I see some support options at the bottom of the OSMand home page, and here (back out and scroll down) there’s an Android sub-forum, which does have some threads about your app. Good luck.
