Lag

I am experiencing more lag and frame skips now than I ever have before in this game. It’s gotten to the point where I do my part in AQ, then attempt and event quest and pretty much just close the game after using around 10 energy. I can usually clear uncollected with a good deal of effort but i can’t clear the last mission or finish master difficulty or the event quest because of how bad the game falls in on itself every time I start a fight. I’m playing on an iPhone 6 with the most up-to-date iOS and the latest update for the game.
