quaff Yeah, I just navigated to a destination, and all the tiles in that view went grey again. If I exit navigation and zoom in + out, some tiles are returned. But I suspect I will have to wipe my Gmap's data once again. Anecdotally, I think this is related to navigation, it's the action I notice will grey out the tiles everytime.
I just closed Google Maps and reopened it, and indeed, the map tiles are grey. if I zoom out, there's a huge chunk of my city that doesn't have any map tiles loaded, but there are tiles surrounding that chunk. I don't know what's going on, but this is definitely not fixed.
Constantly wiping the data is not a great workaround. But I guess at least there is a workaround to be had -_-
