All map exported from RM 2 in mbtiles format has name "Test Name" in Locus Maps on Android. How can I set the correct map name when exporting?

This is our fault, sorry! We are populating some MBTiles meta-data with placeholders but not updating with the name of the map during export. It would seem that most apps that support MBTiles don't actually use this meta-data, as yours is the first report we have received. This will be updated to be the same as the export filename as part of the next maintenance release.

Thanks, Matt.
Now I use the SQLite Editor to change the "name" field in the metadata.

That'll work!
