In 2.6.0 the map loading has a bug. This is the most I could figure out: if there is no maps, but only subfolders in the mapsVector folder (maybe it happens with others map types too), it doesn't display any map. Also, it is not possible to add any additional map folder either in setting or in map "add folder" dialog. Every time I try it there is some "unable to process map" or something similar error.
The fix seems to be to have at least one map in the root map folder.
So if I have
mapsvector
-> subfolder
- map1
- map2
- map3
^^^ it doesn't work.
mapsvector
- map1
-> subfolder
- map2
- map3
^^^ it works. Now it's even possible to add sub-folders to map-watch.
Are you sure?
This works for me:
