So I finally find a way to fix the formatting problem! Hurray! I can’t upload it.
Amazon’s FAQs are completely bat shit about this. One says I can upload a new content file at any time. One gives the impression I have to unpublish the book first. None say it can’t be done.
Trouble is — something’s not right. I can’t upload to Stolen Time regardless if it is published or unpublished. But I was able to pretend to start a new book and could upload to it to my heart’s content. Will keep working on it.
