i have made an app with Open Street Map (located in maps section) and it was working without any problem. but about 3 days ago i faced a problem that it shows only grey grid not showing map. i have created new project and added only the map component to test but again not worked. and also tested with different 3 devices it did not work.
It is a problem that is fixed by the App Inventor developers. The developers of Kodular have to merge the new code and then the problem will be fixed with a new release.
