This game has always run poorly on my iPad (got it early 2017, standard iPad not pro or anything, not 100% sure what the model is but I can look it up if it helps), where no other game or app I've run has had any issues. As time goes on playing it, the condition gets worse until the game crashes, I'm assuming due to a memory leak somewhere.
It used to take a while, though. I could play for 45 minutes or an hour before that happened, which only was during events or a long PvP grind so it didn't bother me too much. Now it's 30 minutes, sometimes less. I didn't even get through my daily quests today before it bogged down to the point of crashing.
I have the latest version of the game, I'm pretty sure my iPad is up to date, and the shortening of time that I can play occurred the exact day Deadshot was released so I can only assume the more assets there are in the game the worse it gets.
Is there any fix to this? I'm on the teetering edge of not being able to play, so if it gets any worse I'm simply not going to put up with having to reload it every 20 minutes (especially since the loading takes longer than any other app I have).
