iOS 8 and iPhone 5C specific issue

So ever since iOS 8 rolled out I keep getting emails from users that our various apps are not working. These are built with different versions of AIR including one we just put out about a week ago with the latest AIR. The one thing they have in common is they are all iPhone 5C users, this is really strange because this issue did not exist before iOS8 and the apps still work perfect on iPhone 5, iPad Mini, iPhone 6 and a full size iPad so I cant figure out why just the 5C would be having issues. Is anyone else experiencing this?
