I'd like to add a point : Even if Android/data subdirectories are not directly accessible in recent versions of Android, they remain very easily accessible directly on the phone itself (ie. not needing to plug an USB cable and access them with a computer) using the com.marc.files application (available on play store) that is only a shortcut to internal application "Files" (that itself remains authorized in Android to browse these "protected" directories).
Another option is to use the "Total Commander" file manager : it is blocked as any other app in these directories, but propose to automatically switch to "Files" when such a directory is selected.
With these two solutions, it's easy to copy and/or to move a GPX track created in a "protected" file to an "open" file.
OK, this do not give a solution to sharing of same maps files by several map viewers (eg. OM Beta ad OM GP), but this removes all other drawbacks having files managed by OM (or any other app) stored in a "protected" directory.
I'm personnally using both (Total Commander, and "internal" Files app via its "shortcut"), and do not have any more any concern with these storage locations.....
