Ive never seen that before. Probably some beta glitch
or corrupted cache, delete/refresh and see if that fixes it. (I assume you're referring to the blacked out board).
Did you try to refresh?
ah i see you're using my 4pc yellow piece set
he is though 🤔
game glitch/bug.
its not the game. Its the analysis
You might've just changed the board color in the settings though.
