Arcade mode unplayable, ranked 1v1 works just fine...

Just like the title says, I can play ranked 1v1 battles with no issues, but every arcade battle my game freezes during the opening screen and even if I try to restart the app and rejoin it just keeps freezing. I was able to play for about 15 secs in a couple arcade battles but eventually it always freezes and I can't do anything. I don't know what to do, it's obviously not my connection because ranked 1v1 works just fine. Hopefully netmarble fixes this soon.....
