I was trying to play a game with my friend, so I invited him to play a friend game. He said he got the notification and accepted it, then the battle started for him. But on my screen it still said "Please Wait." We tried it several times, him inviting me, me inviting him. When I invited him, the above stated happened, but when he invited me and I accepted, it just acted as if I never got the invite, let alone accepted it. Is this some sort of bug? Is there a work around? If not, what am I doing wrong?
