My friends and I will lobby up together, start a match and many times we get the animation of our team standing as match is set to start. Then the game loops a random player in the party back to the lobby while the others are loading in.
Other times, when we finish a game, we wait for matchmaking to begin another game, the countdown timer will go, the match will be found, and then for a random player in our party, the matchmaking timer will restart once again breaking the lobby, forcing us to leave the game and reconnect in the lobby.
We have closed the app and reopened, we have uninstalled and reinstalled the game, we have even reset our routers and still we get this issue literally every other game we play on BF6. Additionally, my internet is 1gig and fully open NAT type.
We are primarily on Xbox Series X but also have a player on PS5 that this happens to as well.
