I'm not seeing any of my PSN friends when I try and import my PSN friends list into Uplay - despite the fact that I know for certain one of my PSN friends was using the GRN app whilst we were playing co-op on the previous day. Hmm.
i can't tag friends either. and my friend's list either partially loads or doesn't load at all. Sometimes it will say that i have 0 friends, but i can go to ubisoft club and see that i do in fact have friends.
