COOP unavailable

Whenever we attempt to join any online mode other than Rush, the game behaves as if my friend is only on menus and not actually in the lobby.

Because of this, we cannot select a game mode or start matchmaking at all. We’ve tried restarting the game, switching hosts, but the problem remains.

Could you please investigate or provide a fix/workaround? This makes it impossible for us to enjoy online Co-op outside of Rush.
