chess.com bug??
Not quite the same bug, but while playing the computer it has made some obvious blunders that average chess players would not make, like losing a queen for no good reason.
It's gotten so bad, I tried going to chess24 but deleted my account their after 1 game. I don't know how anyone can stand that interface.

When playing a game the board does not display properly on an iPhoneX.
I've got the latest software version (14.7.1 at the time of writing) but it appeared on the previous version too.
- The entire board does not display on the screen if i scroll to the left or right you can see another board overlapping the first one
- When i play a move it doesnt update in the game (if there is supposed to be a confirm button then i cant see one)
This is a really poor user experience. It renders the App unusable i'm afraid.

Try out the Zoom settings.

This bug is extremely annoying , I just lost 10 straight games in row. I'm premoving fast but why the hell my time is running even though I've already moved. This is the worst I've ever encountered!!
Upon reflection... I do remember weeks ago a few games where both clocks stopped. It appears as if you’ve been disconnected- but not the case. Happens at peak usage times- as if the server simply stops the game for iOS users as it can only provide x amount of service.
Swipe to close the app and reopen the app. Re-enter your last move and the game continues.
