Why does iBooks claim my iCloud is full when it's not?
I have all the latest updates of OS and programs.
I have plenty of space (+150 Gb) in my iCloud account.
I have logged in/out of my accounts and Apple ID's
My MBP is properly authorized.
Still iBooks claims that I don't have enough space to store more books and PDF's?
Why?
MacBook Pro with Retina display, OS X El Capitan (10.11.4)
