Why can't iTunes12.3.3.17 see newly added pdfs in iBooks?
Using El Capitan 10.11.4 on a 17,1 iMac, cabled to an iPad Air.
I want to sync newly created pdfs in iBooks to the iPad Air using iTunes12, but iTunes12 refuses to see the newly created pdfs. iTunes12 can see old pdf's, but not newly created pdf's made within the last week. I have deleted the pdfs from iBooks and re-added to the iBooks library. I have deleted the .xml iTunes file and restarted iTunes12. I have deleted all plist files from iTunes, and iBooks, then restarted the iMac.
iTunes12 cannot sync a pdf to my iPad Air unless it sees the pdf in iBooks. Why has iTunes begun to refuse to see new pdfs I add to iBooks.
iMac, OS X El Capitan (10.11.1), iMac 14,2 / 3.5GHz Intel Quad Core
