Bug Info: Multiplayer Lobby can be created, however joining an invite is unresponsive, therefore multiplayer is not working.
Platform: Series X
Edition: Game Pass
Attempted fixes: Publishing a support ticket, waited a week or so, reset game etc.
Content Update: We were able to play previously in the past so I would assume the issue started with update 18 or 19.
Are you getting a “something went wrong” error message as in this report?
Or another error message, or no message?
