I am having issues synching Numbers documents on my iPhone 4s (iOS 5.1.1) to Numbers docs on my iCloud account. I have deleted and reinstalled Numbers on my 4s and have shut off sharing to iCloud and reactivated sharing to iCloud. I've tried synching over 3g and over WiFi. Nothing seems to work. My other devices with these Numbers docs are a the New iPad (iOS 5.1.1) and Touch Gen3 (iOS 5.1.1). All of my devices are running Numbers v1.16.1. What am I missing? Any help would be appreciated.
