Unavailable with party - Multiplayer not possible?

Yes i am getting the the same issue. This is on PS5 i have checked that well all have the same settings. We found a work around which wasn't perfect, basically the other 3 squad members enter a gane you you join them after. 

Or 

Host the game on your own, then select the mode you want, go to the squad screen then let teams mates join you, and launch the game then...dont do back into the mode selector screen.

On PS5 pro. Received same message exactly 2 days ago as well. Still currently having issue.

Same issue on Xbox. Whenever I try to select any multiplayer mode I get prompted to buy Xbox games pass which implies I need to pay extra to what I already payed for full game. 

Same here, my whole squad has this issue and we can‘t start a game together. Honestly this is a game breaking bug because how are we supposed to play, when others have no problems. And how are we supposed to play the new Battle Royale mode? This is just stupid and they have to fix it.

Leave the affected party so you’re then in your own party on your own. 
Browse game modes and select the one you intend to play together, Conquest for example. 
now back in the lobby you have the option to Start but don’t just yet. 
now invite your friends into the party, once joined it may show unavailable again at the top of the screen but it allows you to select Start. 
This will start the preselected game mode with your now party :)

Works on PS5 anyway, 28/10/25

Same problem for ps5

Same problem both on PC (Steam) and Xbox. 

Same on ps5.

Yes, I have same problem if I'm on group with PC players. I have activate croosplay. Time to time I cannot join to group if is group is not full...

I have the same problem. Only solution to play togheter is when I'm concrete lobby and my friend joining to me in that moment. When I only leave lobby I have locked all modes to play with my friend.

We are playing on EA App.
