I Had two bugs . 1. Between siding in match duel i could not see any cards at all in ranked ! 2. I started round and in my opponents turn i could not press anything, time run out , i could not even press surrender. I saw side deck but i could not press anything at all too. I tried to reconnect ! i quit game and restart and it not joined back.
This bug is acknowledged and already fixed in future version and will be shipped with next update. Thanks for your report.
