Game Won't Matchmake

It’s been about 4 days since I’ve been able to play a multiplayer match. I click “play” and I goes to the waiting room, but it doesn’t show the lobby filling up. I waited for 30 minutes and it doesn’t find anyone. I’ve also had some instances where it will finally matchmake, but never loads, and restarts the matchmaking process. If you have any tips on how to fix this, please help. I wanna get the challenges done.

Have you tried 4vs4? I have the same problem with big team games but at least small ones seems to be working

Can you check an make sure that your game is fully up to date with the latest updates and hotfix? Your build number should be 1.2046.0.0

If you are on MS Store, you may need to search for MCC on the store and update it from there. Once you’re up to date, try enabling all the available games/modes that you can in the match composer and also make sure that platform based matchmaking is disabled. See if that helps you get into games now.
