Yesterday, my brother and I tried to play the main game in Coop but we couldn't.
Same problem happened when we tried to connect in Guerrilla and Online match.
Last time I tried to play Coop campaign with my brother (about a month ago), we had the same problem. The only mode i can play online is Conflict and I cannot invite any friend for a match or join their game.
Is the Ubisoft servers not working? is this a problem with the Uplay account?
Anyone experienced this kind of trouble trying to play Coop?
