There are several possible reasons:
- The text is not paginated with the paragraph indent;
- Inside the book, there may be a picture that exceeds the 3,200,000 pixel limit;
- The cover has a side smaller than 1400 pixels. We advise you enter a cover of at least 1875x2500 pixels so that it fits all our partner stores' requirements.
- You have images in CMYK instead of RGB (Apple only accepts RGB, which is a better choice for digital images)
If your book doesn't have any of these elements and still isn't available on the Apple iBook Store, we apologize for the inconvenience and please contact us at firstname.lastname@example.org so we can sort it out with you.
