You are right about the mismatch speed - I have raised a bug and will get right on it .
The castling is an odd one. Going to look into it but I think it is probably the play board.

The chess.com screen does not register the move when I set the king down two-squares over. It's not an issue with your software.

I asked @KevinTheChessGnome a similar thing. When castling did you move the rook after the king? Or did you just leave the rook in place?

Move the king two spaces and waited for chess.com to recognize it as a castle. It's been the only "safe" way to castle on chess.com. Otherwise you may end up with a unintended rook move.

I've think I have figured it out. See this post.

Here's a game with the 11/21/22 drop - https://youtu.be/Csn55B7mr4c
The audio not playing late in the game was a hardware issue on my end, when I turned the 10" monitor off/on to stop the flickering.
