Running Hearthstone on an Ipad Air 2 and after about 7-8 turns in any game mode the framerate drops to about 1,making it impossible to use hero powers and cast cards. If I hard quit the game and restart it will normally fix itself,but then happens again in the next game (obviously lose the previous one because I miss so many turns restarting). It’s clearly a RAM issue but I should have 4gb, which is plenty. I’m up to date on OS and have uninstalled and reinstalled the game multiple times but has made no difference. Any info would be great. Thanks
