For nearly 3 hours i tried to jump into a lobby with my brother to play through campaign and just to check we also couldnt join into a custom game either which raised red flags.
We tried to power cycle the system (no Dice)
we tried closing the game and retrying(no Dice)
I just would like a confirmation from somebody who knows what they are talking about to respond with an answer
yes. this issue is more of a concern for me than matchmaking as I and a group of friends primarily want to play custom CE matches only. Nearly impossible to get each other in the same game.
