I just logged in and went to play a live game, and as soon as the game started an advert appeared in front of the board, with seemingly no way to remove it. It then expanded to cover almost the entire board, obviously making it impossible to play.
The only thing I remember about the ad was there was a fox and the voiceover said "These are the lands..."
If it happens again, you should get more details and report it so it can be removed.
