Ive figured it out, everyone!!! The upgrade is actually not bad, I have figured out what you need to do to make the game run smoothly. In your iPhone SETTINGS, turn OFF "Background App Refresh", "Cellular Data", and "Enable 3G", while playing. (Just turn them all back ON, when youre finished). If you do this, the game will run flawlessly and smoothly :-) Please post a review, advising if this helps…
