Party connection issues

Not sure if it’s been addressed, but I’ve been struggling to keep a party. I have friends join, we play a match, then it glitches out and keeps us stuck on the end game screen. Or it keeps one of us stuck on the screens then loads the other into a game.
Even when they join a separate game it still keeps us in the same party. It’s just frustrating having to exit the game, make sure everybody is in the lobby then start another game. It should just keep matchmaking after every game.
Is there a fix I’m missing or is it just broken?
