Sorry for the newbe question: I use iCloud only for a few Pages documents, just in case my computer crashes or is stolen. When I use Pages to add to or modify a document it doesn't show the change in iCloud. The help section saids "you can edit the document from any iOS device, and the document is updated in iCloud and all other iOS devices." But this isn't happening. How can I sych? I've tried "save" in Pages but that only changes it in "My Documents".
