I’m not sure if this issue has been seen before, but I was playing a bot on chess.com on ChessUp 1 connected to an iPhone. At one point after making my move the app showed I made another move with another piece and furthermore the bot in the app responded with a move that the board then didn’t recognise, so it was a complete mess. Takeback didn’t work and I had to resign the game to get out of it. I really can’t figure out if this is the app, the board or chess.com messing things up. I hope this can be clarified.
We have not seen that before - that is weird.
There is a slight chance the board misregistered the move.
If you can capture the bug happening (screen shots, picture of board) - we have a bug report form here:
Sure, I don’t know why I didn’t think of it, when it happened.
