I am still unable to find out if KDP really does automatically fix uploaded files in the same way. I uploaded my test book and it just sits there in my bookshelf flagged as Draft, so I can't buy it. I tried emailing them but received no reply.
Has anyone here got a book that goes to the wrong start position when they view it on a Kindle 3 (that has been upgraded to KF8), that is available for purchase very cheaply? If so I could buy it and find the answer. An expert could then compare the book that was submitted to the book that was purchased and check exactly what KDP are doing.
