While playing minecraft in cross platform between xbox and windows 10/11 there are initially no issues connecting to a game. however the same cannot be said for playstation. When I or my Fiance either try to invite someone on the playstation platform to one of our game worlds on either windows 11 or xbox it does 1 of 3 things. 

1- It simply does not go through to the playstation player.
2- It sends the game invite and they cannot join,
3 it sends the invite and it allows them to join for a few seconds before booting everyone but the host player from game.
