Can someone tell me, please, when you've downloaded the KML of your unexplored tiles to the maps.me app (for iPhone), how do you get rid of it? It's now out of date, but opening a new KML file doesn't get seem to overwrite the old one...
ETA: it's OK, I've found it - the file was added as a bookmarks list, so I just had to go into the bookmarks folder and delete it.
