Okay this has gotten really annoying but i have an Iphone 5c and Fallout Shelter will not give me the option to use Icloud, that should be set up next to the shelter in the vault list. My Iphone 4s has that option but not my 5c plus they're both connected to the icloud both Icloud Drive, i doubled checked it. Now the only difference between the two phones is that my 4s is updated to version 9.0.2(13A452) and the 5c is updated to 8.4.1(12H321), I'm not sure if that has anything to do with this specific issue but if it is let me know.

Otherwise it would be greatly appeciated for any help you give.
