Maybe someone else has had luck with this and can clue me in on a solution: I absolutely love the ability of Storyist to be able to export a PDF in a trade paperback friendly 6x9 format for publication through Blurb. However, I don't use Blurb because I prefer to use Amazon's KDP paperback option. However, when I attempt to upload the PDF to Amazon, it always spends about 15 minutes "processing" the file before it finally just says there was an error with the file. At which point I end up having to copy and paste my book into word, re-formatting everything, and creating a PDF from word. Is there something I'm missing or that i need to tweak in order to get the Blurb PDF file compatible with KDP paperback guidelines? On paper, it's theoretically the right size and bleed and everything, so you'd think it would work. But I've tried it on three books and none have worked. Thoughts?
