Hi, everything works fine for me. I installed MK8 + Updates + DLCs and am playing online for days now. However, my friend did the same today. We added each other through Wii U's friends app and I can see him in the list when I proceed in MK8 to online mode and friends mode. But: He can't join my room and he can't create one on his own. When I open up a room and he clicks on my face in the list, the "join" button is greyed out. When he tries to open up a room the A button is greyed out so he can't create a room for me to join. However he can play normally online in GLOBAL. Really odd. Does anybody knows a solution?
