I've always used 'guide' tags by putting the epub of the book in Sigil. I'm always careful to put where I want the book to Start right after the TOC, Amazon seems to choke if your start point isn't after the TOC for some reason. They probably have a rule about that in their Formatting Guide. Then I add the guide tags beginning with Cover, Title page, TOC and then 'text' which is my Start id for Notes, Prologue, Chapter 1 or whichever point I want Amazon to flag as the Beginning. Sometimes in the content.opf the guides loose their order and I go back, take off the guide tags and re-do Cover, Title page, TOC and lastly Text. I've never had a problem with my own books or any of the books I format for others. Just saying. This is probably too simplistic, but it works for me and has for years.
