Martin_Stahl,
Can you advise on (i) how to force an update, as I've tried deleting/installing to get latest version, and still get problems ? (ii) I've had - frozen clocks (both players), moving clock- mine - but could not move piece, moving clock - opponent's - and he/she could not move piece, and able to chat all the time i.e. if it's wifi, I should not be able to chat. I've worked in IT and it smells like programming problems, possibly network related e.g. 12,000 games running on a system which can handle 10,000 i.e. it misses out on polling your game, because other games are more active etc.
Some very bad players on this app was winning hands down and he stopped his clock to win the game remember this name
[removed -- MS] french player don’t play him he is a cheat!!!!
Your opponent can't impact your connection at all. There is a known bug in the previous iOS app; there is an updated app that came out yesterday, so you should update if you haven't already.
