Diamond Dynasty won’t work

[Mr Kalaspuff_XBL]

Experiencing this same issue, It wasn't always this way for me but it has now been like this for over a week. Also tried everything that has been suggested in this thread with no effect whatsoever. Can play other game modes and every other game just fine. Trying to remain patient but at this point I don't even know if I should expect to ever be able to play again. Submitted a ticket but got a response that didn't really give me the impression that they even read it. Also submitted another ticket where I tried to be even more detailed but so far no response. It is a shame as I really enjoy the game and DD in particular. Not so much angry as disappointed. If there is anything that can be done to fix it I would just like to know what that could be.
@Collin_SDS_PSN , any idea what could be going on?
