iBooks - edited data not syncing to other devices
using iBooks, iCloud, El Capitan, all upgrades are current - recently I edited all iBooks data on the iMac. Expected this data to be synced to my iPad Air or iPhone when I plugged them in overnight. Nothing happened. Still waiting. They are showing only partial lists of the documents with the old document names, collections and categories. Tried deleting complete app on the iPad to then have iCloud re-establish it, but iOS would not let me do this. Can't even delete individual documents from iBooks on the iPad.....they all show the Cloud symbol, but the old names etc.
iPad, iOS 5.1.1, 27" Mac; Airport Express; OSX Mtn L
