    Very bad lag in combat. It is like playing in slow motion. Only started happening with this update. Am not able to play the game any more, have deleted it off my phone. Not sure if this is purely because of my older phone, but a week ago before the update it was working fine.

    The game starts with no lag until you either exit the game and then come back (without closing the app) or you get a notification or just opening the control center. And rarely lags mid fight for no reason. Please fix the issue its really causes me to loss resources.

    Game Mode...Pick one!
    Issue... I can no longer log into the game. Before that, it was horrible lag and distorted graphics. Fighting controls worked 50% of the time. Block fails to block, or it would throw me forward.. I could go on about the controls but you did not fix them even after 2 support tickets, so I won’t waste time typing them all. Just fix the game please!

    Can we get another update on the situation please. Will there be a fix in the immediate future or we just gonna keep rolling with the game as is for the time being.

    I have iPhone 6 iOS version 11.3 issues occur over both cellular and WiFi, game version 19.0 according to uk App Store last update was for the new antman eq
    Current issues are: sluggish champs, game lag in all fighting modes and also when moving between champs screen crystal screen store etc items in overflow do not show correctly for example a t5 iso often has the image of a tier 1 or 2 iso, champs randomly stopping mid combo dash back just not happening, screen over heating constantly and a 100% battery draining completely after only 1 hour of game play,

    I have the latest iOS on my Ipad Mini 4 and until the last version the game works like a charms now with the last update is impossible to play latency in aq and aw kill me all the time plus the latency to block opponent is impossible in this way i can't play the game anymore so I have to leave the game please make it something quick and fast to fix latency issue in many iOS devices.... thanks

    PS. For your info as a iOS developer I can tell that the game start good and is deteriorating every time you play AQ or AW so seem like a leak of memory that after some time crash the game.

    Device and Model: iPhone 7 Plus
    Device Operating System: iOS 10.3
    Cellular or WiFi: Cellular
    Game Version Installed: 19.0.0
    Game Mode: AW/AQ
    Description of the Issue:
    Mostly happens during alliance war. Some controls don't function and sometimes there is a lag. There are delays in blocking, evading, and attacking. It is sometimes frustrating to see your champion punching and kicking air. No problems during arena fights though.

    I have been reading some posts here. It seems these problems have been going on since April. Are they working on a solution to these problems? Or did the complaints fell on deaf ears?

    Game is lagging and glitching during fights in AQ, AW, event quests and arena. I am losing easy fights caused by missed blocks and evades because of glitching.

    Put phone into power save mode it fixes the performance issues I've tested this on both iOS (iPhone 7) and android (Samsung s7 edge, Samsung s6)
