I feel distressed! I have used Locus Map for more than two years with barely a fault. I was walking on Thursday when my GB map showed map tiles loading, suddenly. I did not know what caused it but thought it was a blip of some sort because I have not once had such an issue. Now at home, the same situation is continuous. I can zoom out (13) and the whole screen displays, but slowly. Zooming in (from 14) or panning, a map tile is either frozen or a number of map tiles display, "Loading..." but nothing happens. My set up and content has not changed, essentially. Nevertheless, I have deleted all folders containing my specific tracks and boundaries; I run CCleaner every day; I have tried another mapping dataset; powered off and on my 'phone; cleared the cache in Settings/Apps. I have been aware recently, too, that Locus Map is taking much longer to load upon startup.
I understand this might not be a Locus Map problem as such, but this forum has such experts, I wonder if someone might be able to help.
