App used to run flawlessly but the past few months it has been plagued with constant issues. Game either crashes or freezes almost every match at this point. Has cost me thousands of gems/coins because by the time I realize the game is frozen and relog, it's already counted it a loss. App runs just fine on PC but I find the mobile app's issues absolutely unacceptable for a game that requires so much time and money to play. Take my recommendation and save any events or ranked games for PC.
