I just got the app yesterday but was an avid player on the computer and became very good but every time I play the required novice arena match as soon as Im about to win they close the app or something, and I get a message about a connection failure when I shouldve won the game and unlocked normal matches make a system where if someone disconnects the other person wins. Also, there is NO ONE In the United States servers when I went on I was the only player, and when I go on the Chinese server I have 500 ping which makes the game lag and hard to enjoy either make one universal server, get more people on the U.S. server or make the ping better.
