from https://www.reddit.com/r/APhotoManager/comments/cdicfq/map_not_showing/

For me the map is not showing. I do see the pins for my photos, but the map stays empty. I am using version 0.7.3.190424. In the log file, I see a lot of the following:

"Please configure a relevant user agent; current value is: osmdroid"

Any idea how to debug this?

The Openensteetmap servers are now blocking map requests for apps that do not have properly set up their setUserAgentValue (who/what is using Openensteetmap)
