Haven't had this problem at all, I've been playing past 5pm though.
I guess it might be the time I'm available to play at, because that's always what I'm experiencing. Ranked match? "Failed to connect" or "The match has been cancelled." Player room above 1 connection? "Could not find a room..." A lobby? "Failed to obtain room information", "Host is not responding" or there are only Japanese players.
Seriously frustrating. All I want to do is play so I can improve. Seriously putting me off playing Xrd; I hope there's a lot more activity when it's actually out in NA.
