iCloud storage in iBooks has been working pretty well for me in beta 3, but some books refuse to be downloaded from iCloud to iPad. They’re correctly marked as iCloud titles in the iPad iBooks UI, and I can tap on them to download the book. I see the book cover dim as normal; the download progress bar appears and completes; and then the book unhighlights as usual. However, when I tap the book to actually read it, I receive the error message shown in the attached screenshot. The book status then resets to show the iCloud icon.

More than 10GB of storage is available on the iPad, so this can’t be an actual storage issue.

This seems to happen with about 50% of the existing iCloud books. If a particular book is stricken, it will never download properly despite repeated attempts. And if a book doesn’t have the problem, it can be downloaded and deleted repeatedly without provoking the issue.

Deleting a problem book from OS X iBooks and then dragging back into iBooks to reupload it seems to consistently fix the problem. I should note that I turned on the iCloud functionality in the first betas that supported it for both iOS and OS X. Both devices are currently up to date on their respective betas.

Some console logging data is below. First, this log output is produced during the download phase of a “bad” book:

And then after tapping on the book to open it:
