Hi
@bybyfriendsThis happens sometimes because of the delay in transmission of moves due to bad connection. Suppose your opponent made a move and your internet is not working great, your opponent's move will be shown to you after a while and till that time, you will see your opponent's clock decreasing. But when the moves will be updated, you will be witnessing an increas in the opponent's clock since he/she had played his/her move some time before.
