I set to download this to my iPhone 5 with iOS 8.1.1 and it is just waiting to download for the last 24 hours. Not sure how to get past this problem. Any ideas?

The game size is 680 megs, i had the same problem trying to download over the air, connected to my itunes, downloaded via itunes on computer and then synced, no problems, i suspect it is due to the game size that it just WONT dl over there air

Yes , I cancelled the download then did it again while connected to my pc and it worked.

Thank You
