iBooks not syncing with iTunes
So several days ago, my books disappeared from my iTunes. I can still see everything in iBooks on my computer, but iTunes won't recognise them. Also iBooks from my computer is not syncing with my iphone and ipad, and for now the only way to read something is if I upload it to icloud drive and download it on the device.
Also in iTunes - there's no BOOKS tab, it appears only when I connect a device, that's when I see that the books are not in iTunes and i can't transfer them to the devices. Is there a way to make my books from iBooks, appear in iTunes?
I am running:
OS X El Capitan - version 10.11.4
iBooks - version 1.5
iTunes - version 12.3
Thanks!
OS X El Capitan (10.11.4), null
