Just did some of this myself, had my sign down for a good hour but nothing was showing up. Not sure if this helped or not, but I quit a few times on each console and reloaded the characters and eventually they showed up together and summoning worked without issue. Again not sure if that helped cycle through different servers or not, but that was what I was doing at the time it happened lol.
I really wanted to get it to work because I wanted some help fighting Sif, little did I know 2 whole Crystal soulmass shots would kill him...lol. Almost wanna start over with a melee character because this magic stuff is making it to easy
