Maps, airspaces, waypoints blank since v2.1
After updating to v2.1, my downloaded maps (open maps), waypoints and airspaces are not displayed on-screen. I get a correct elevation graph, and all menus and buttons, and if I tap on the screen I get info about the airspaces where I tapped, but I can't see anything other than a white background instead of a map, and a grey circle where the compass / orientation selection would be.
I have deleted and reinstalled everything three times now, switched between SD storage and Internal storage, etc., to no success...
I can provide screenshots if needed - I just can't upload them here for some reason.
I'm using the app on an LG G5, running Android 7.0 (Nougat).
