Is anyone having issues with the MCC matchmaking? First the game didn’t even started the search, then it started but didn’t found anyone, now it’s finding players but the match won’t start and it resets the search everytime.
Was literally just about to start a forum about this….because I’m having the same exact issue. My Spartan ops also aren’t showing as complete each time I beat one
Ahaha yeah I also been having this problem keep finding full lobbies and it restarts the search 
It’s a known issue right now and 343 are working on a hotfix
