I've noticed a few problems also
- Sometimes after making a move and it automatically moving to the next game it does not show your opponents last move. I often have to close and restart the app to be able to make a move when this occurs.
- In one game I was unable to move a pawn two spaces.
- Upon making a move in the last game where I need to make a move it often freezes and then crashes.
I love the new interface however.
A problem with the latest version are making it close to unusable at certain times:
Castling - when the last move is your opponent castling it moves the king an extra square over.
