I recently created a Pages document on my Mac (OS X 10.8.2). I then opened it in Pages on my iPhone (iOS 6.1) to email it to someone. iCloud downloaded the document as expected when I opened Pages, but when I tapped the Edit button, and selected the document, the "Share" icon was greyed out. The "Duplicate", and "Delete", icons work as expected. I also tried duplicating the document before sharing it, with no success.
Is it possible to share Pages documents that were created on a Mac and synced over iCloud from an iOS device?
