What platform are you on? I'm on Android 8.0 and I see the map. Does you area show up on openstreetmap.org ?
I'm a novice user so I mostly click around confirming crosswalks sidewalk materials :p
AOS 5.
My area is well mapped if that’s what you’re asking. The openstreetmap.org is no longer accessible because it became a Cloudflare site, but OSMand shows that the map covers the area I was in back when I tested Street Complete while online with GPS running. That test was actually a few weeks ago, before openstreetmap.org became a restricted access website (so Cloudflare is unrelated to this particular problem).
Do you have ideas what could be causing the issue? Like I said, I'm a novice, and by the sounds of it you sound like you know a lot more about this ecosystem than I do.
Really hoping for a dev or someone to wander in here...
The only thing I can think of is that my phone forces all traffic over Tor. It’s possible that wherever StreetComplete goes to fetch maps may be a Tor-hostile server, and StreetComplete does not bother to inform the user. I could try making a config exception to direct StreetComplete traffic to the clearnet. Maybe I’ll try that the next time I have an unlimited connection at my disposal.
This would be an interesting test for others to try: use SC with tor and without tor and see if there’s a difference.
OsmAnd is a great open source Maps mobile app that uses OpenStreetMap!
