Every round had a black screen, but I don't know if my opponent also saw it or did he have a location. Leaving and rejoining the game resulted in nothing. My opponent won. After checking the locations in summary, every single one was a black screen and on the bottom of the screen a message was shown that "This place has no street view". I lost 17 points from my score.

Basically we were shown locations that seem to be non existent.

I'm providing a summary mentioned above here: https://www.geoguessr.com/duels/690650503117ee413e0f88c9/summary
