Keynote will not sync with iCloud
Everything appears to be installed correctly -- calendars and contacts are syncing back and forth between iCloud just fine. Within the iCloud settings, Documents & Data is set to "On".
Under Keynote settings, there is a toggle simply labeled "iCloud". When I turn that on, leave the settings app, and then return, it is turned off. This happens on both the iPad and my iPhone.
I've checked the settings under Keynote, iCloud and Mail, Contacts and Calendar several times, and there is nothing glaringly wrong there.
Has anyone else had this problem and determined a fix?
