I'm working on an EPUB version of a friend's book, and I'm finding it impossible to get the EPUB to load on Apple devices, even though it passes every form of validation I'm familiar with, including EPUBCheck, Calibre's validator, and Sigil's validator.
On one tester's device, it gives a message saying "Book content unavailable"; on my own devices, it shows every chapter in the book as a blank page.
Has anybody ever seen this before?
