I am having issues where the static content is loading very slowly. This includes the card images, game background, and the Victory/Defeat screen. In fact, the Victory/Defeat screen loads so slowly that my opponent leaves the room before I get the chance to say "GG" or offer a rematch.
Having to wait 20 seconds before the results screen appears is kind of a big deal, you can't rematch, and your opponent can't tell that you haven't loaded the results screen yet.
