[PC] Cannot Join/Host a Co-op Lobby

My friends and I are trying to play Ultimate Team Rush but whenever someone tries to join a lobby they get a "This lobby is no longer available" message. We all play on PC, we've tried restarting Ultimate Team, the game itself, and our PCs but nothing has worked. This started happening after the latest patch (v1.3.0).

Any suggestions on how to fix this or an ETA on a fix?
