As I was playing a game a big ad popped up on my screen and the board disappeared. I was not able to make a move until an X appeared that I was able to click on luckily I was on the path to lose the game but if it had happened in a quicker game I could have lost and it would have been very upsetting.
If that happens you should report it. Those types of ads should not occur
