The publication Preview in this asset contains versioning info. Please export the sample without a version and redeliver.

Please try this.

The xxx.opf file in Sampe.epub must have a line which looks like

Remove that line, save the file, rebuild the package and deliver.

Sorry - I am having the same issue. From where exactly do I remove that line? Thank you.

What are you using for creating your book? iBook Author??

If you are creating your book using iBook Author then following are the steps to remove the versioning info in the publication preview

1. With the book open, choose Share > Export, and click iBooks.
2. Choose Standard Book for iBooks from the Export As pop-up menu.
3. If you want, type a book version number in the Version Number field.
4. (DON'T put any version number here. I think this is causing the problem)
5. Click Next.
6. Type a name for the book, choose a place to save it, and click Export.

But If you are NOT using iBook Author then you must have an epub with you then you will have to remove the versioning info from your preview epub.

There must be xxx.opf file in Preview.epub, I will have a line which looks like

Remove that line, save the file, rebuild the package and deliver.

Thanks,
