Pieces are missing

Has anybody had an issue trying to play were all the pieces are missing. It happened once so I aborted and checked to see if blind chess somehow turned on and it wasn't. So tried to play another game and same issue

Could be a connection or performance issue.
Sometimes, when my tablet is overloaded, I see the board but no pieces.
The time goes down, but I can't (or better don't want) to play.

Could this be the reason in your case?
