After this update, somehow, the "sound" that tunes up when you finally find an opponent is gone. Please do bring this back as it could cost games. Some people (like me) browse FB or other sites while we wait for a battle since 3v3 takes quite a time to find.
I wasn't aware about the signal that the battle has started was removed, and I ended up missing 1 turn (realized it because I heard the clock tick) in a 3v3 fight, and that 1 turn costed me a battle. (that wasn't very pleasing because it dropped my rank drastically)
So yeah, please do bring the "sound" since it helps us alert that you have found an opponent. Thanks!
