Remove all iBooks 4.6 (3430) documents & data
How can I delete all documents and data in iBooks 4.6 (3430)?
Settings > General > Storage & iCloud Usage > Storage: Manage Storage > iBooks shows that 1.4 GB of Documents & Data are consumed. My goal is to reduce this to less than 100 MB.
In iBooks I've selected all two items in All Books and have tapped the Delete button. The items now exist with a cloud download icon
I've also gone into iBooks on OS X and have hidden all extraneous purchased iBooks.
Settings > iBooks has the following settings changed from default:
Sync Bookmarks and Notes: off
Sync Collections: off
Online Content: off
Settings > iTunes & App Store has AUTOMATIC DOWNLOADS Books set off.
I've restarted my iPod and iBooks is still consuming 1.4 GB.
