ibook submission
Apple
if someone does not own an Apple device you do NOT allow that author to import an epub document to idrive and pages. You expect one to recreate a book from scratch -might be one reason iBook far behind kindle books which is device agnostic
At the very least put in your article https://support.apple.com/en-us/HT208716 on how to publish an i Book a statement stating, so folks arent wasting time calling you or looking thru your forums
"We do not allow you to import an epub document into Pages so it can be published, you must create one from scratch, buy a Mac or take your book elsewhere"
