Yes. You made use of abort too often. It is only supposed to be used rarely, because you started a game by mistake or for unexpected life situations.

The option will come back after a number of games.
Has anyone else had the "abort" option is no longer present when playing a game. Usually you can abort a game if you haven't played a move yet, and after you move, "abort" changes to "resign." When I was playing today however, I noticed that the abort button was replaced with the resign button at the start of the game. I know this isn't just me because one of my opponents resigned before they made a move in one of my games. Is anyone else experiencing this? Does anyone know why this change was made?
