please fix chess.com. puzzles on IOS glitch.

There’s a glitch on IOS where I couldn’t castle queenside in a puzzle (I don’t have the link, but the puzzle’s rating was 2150). I think that the reason it wouldn’t let me castle was because the b1 square was controlled by a rook on b2, so that meant I couldn’t get the puzzle correct. By castling, my Kc1 would attack the Rb2 and the Rd1 would check the king, but it wouldn’t let me do that. Also when it had shown solution, it actually didn’t play the last move because the game claimed it illegal, even though it was correct. Hopefully chess.com fixes this so it doesn’t cost others rating points.

I know there is a castling bug on Lessons. May be related to that.
