On pc game pass version
Me and wife can’t join games together I can on my own but on hers she is getting a error stating she is offline and needs to restart the session to be online we have tried and nothing has worked we have tried reinstalling and does nothing restarting pc Doesn’t work ether I have allowed it thru fire walls and everything not sure how to get her multiplayer working we are on same network as well
In the past me and my mate had a similar issue on playstation. If the one, who followed an invitation, already had started the game, it lead to this error.
If we followed the invitation from the consoles dashboard, it worked.
This issue was resolved for us long time ago.
Maybe it’s something related to apex connect. In the last days I noticed that I wasn’t able to fast travel to my bases sometimes. 
yea not sure with us being on pc i did try that like invite then use that to load the game but sadly it does the same thing and says i left the even though i am on the game in the same room
