here the same thing, it was happening since the beta. I'm trying to play in a party with a friend of mine and when I click start, sometimes he gets pulled into the game when queuing and sometimes he is left behind in the lobby.
It also happens after a game, when the game goes to a new map, I go into a new map, but my friend is left waiting. Sometimes he gets pulled into the new match. The things is, in the beta it was happening constantly, now in release it like 50/50. So each time I have to quit and start a new match and see he gets pulled into that game.
It has reached a point where my friend doesn't want to play at a certain point, because he is fed up by this bug. So EA please fix this!
I gave BF6 a chance after the horrible BF2042, i guarantee you that i won't buy the next game if this issue is not fixed
