I have a Fenix 7 Sapphire Solar, and I have a rather strange issue. The watch will only download two Outdoor+ maps at a time. If I add any more than two to the queue it will download the first two, but then the next one will permanently be stuck on 0% even when left overnight. Even with the watch saying it has15GB of space left.
Until recently I had issues with the watch not downloading any maps and the device saying cannot unlock maps when starting up. this problem occurred when the watch was accidently unplugged while a map was updating, corrupting the file. I followed the advice in a forum here and managed to fix that. but Outdoor+ still is not working correctly.
If two Outdoor+ maps are already installed then any other map that tries to install will just be stuck at 0%.
