I don't seem to be able to synchronize my iPad (2) and IPhone (5s) to access the iBooks documents saved across the devices. They are both updated to the latest iOS. I Have looked into all the settings and they all appear to be OK, but still don't know if I am missing to set the the ones that engages the iBooks. I noted that in the iCloud "settings" I don't see the iBooks icon as I do with the Photos, Mail, Notes, contacts, Calendar, etc., which I manage to see across devices.
However, I don't find a way for iBooks to add it or for making it into my iCloud Settings screen menu.
Can I kickstart a sync to get iCloud working for iBooks?
