Problems with Party Matchmaking?

When I try to play the game by myself I don’t have any issue, and when we’re playing games that don’t need matchmaking, such as co-op campaign and Firefight when we have a party of four it works perfectly fine. However when I’m with my friends in a party and we try to play normal matchmaking we often have errors of players getting randomly kicked out of the party, matchmaking randomly stopping and going back to the multiplayer lobby screen where you select game modes and game size, or worse of all, we queue up and we get sent into different games.
We’ve had instances where I was queuing with my roommate and he got into a SWAT game while I got put into a game of Grifball, and just recently we were queuing up with another friend, and my roommate and I got returned to the matchmaking lobby while our friend got put into a SWAT game.

This is very frustrating and has made playing multiplayer together with my friends virtually impossible as these errors happen far more often than us ever actually getting put into a game together.

Hey, having the same problem. My dad originally bought this game for me and him to play split screen like how you used to with reach and ce but we can’t even do that. So he bought me a copy so we can play together, we are pissed!!! Partying up keeps kicking us off and calling it an connection error. THIS GAME IS BROKEN!!!
