iBooks don’t download
Get error message not enough memory I PAY FOR 2 Gigabytes memory ..
only have 200-300 iBooks ...How can there not be enough memory on iPhone and or in iCloud?
iPhone 6 Plus, iOS 7, iOS is 8.1.3
It's not how many iBooks you have installed, it's the file size of each one. Rarely are any two the same.
