In the update when the new UI was added (April I think it was?) there was a brief freeze (a few seconds) when starting matchmaking or selecting campaign missions. Since the October XB1 system update, the length of that freeze has increased over time now such that I can’t play multiplayer at all. Any advice for fixes or if the new UI coming with Reach fixes this issue?
I currently have this problem on my X, but my S in the other room plays the game fine. Sorry I can’t be of help, I tried everything I know of at this point.
