Hello. All my favorite points have disappeared from the map in OSM AND app one day (stopped showing up). I had a thousands of them, so I’m very worried. They are still visible on my phone in a OSM folder as files (when connected mobile phone to the computer), but are not displayed on the map. Hovewer, a new favorite points are saved and are visible on the map What can I do to restore old favorite points to the map?
I would first recommend backing up your favourites file(s) to your computer before anything else goes wrong.
Have you recently changed the storage location in the app or had an operating system upgrade? Do newly recorded tracks save to the same folder structure as the old favourites file?
If the storage location has changed I think the old favourites might have become “orphaned” in the old folder.
OsmAnd keeps backups of various files inside the OsmAnd directory in a subfolder called “backup”. There you should find files named similar to “favourites_bak_.bz2" or "favorites_bak_.gpx.zip”, depending on your OsmAnd version. Check if you can recover your favorites from these files.
