Hi Guys...
Got the same issue....
Cant play Online.
i got it to work. a guy found this:
"i got it to work by going to my games in console companion and clicking start game from there"
BUT!
I cant play with my girlfriend. We played one on xbox with game pass, and one on PC with steam. Two different MS accounts.
Now i can play with my MS account on PC, but i use the game pass....
So my girlfriend cant play on game pass on xbox anymore...
AND i cant use my steam save....
