I recently tried to add my friend to Uplay, which was successful. He then accepted my friend request. When I went to see him in my friends list it constantly says he is offline, and I cant see any of his ghosts? He is on PS4 and I am playing on the PC. I understand there is no cross play so we cant race against each other in an x-cross or whatever, but shouldn't I be able to see his ghosts? And see him online?
