yeah that is happening to my friends iphone as well...he can play the computer just fine and he can see me (i have an android phone) and he can start and accept all games and even do the analysis board during our game but he cannot move his pieces at all. WTF?
IPAD TROUBLE

can you try to close the app and restart it? if that doesn't work, try a reinstall? if that doesn't work, we have problems...
Erik------this is not an app. I am playing turn by turn, correspondence style so it is being played within SAFARI and have never had a problem before upgrading to recommended os for ipad
Ipad cache, along with cookies, and problem persists, can this problem with Safari be due to updating the IPAD's os? I can always use the app, but I sure had no problem using Safari to play chess.com's "online chess" prior to updating as Apple suggested
I just updated the operating system on my IPAD. Now everything works on the chess.com site EXCEPT I cannot highlight a chess piece or pawn and cannot make a move. All other features seem to be working. This problem seems to be confined to online chess; live chess is just fine. My Problem or fault somewhere else? Help please!
