Issue exporting PDF for Amazon KDP
I successfully exported a manuscript in KDP. We made some changes to it, and now when I upload the manuscript, I keep getting upload error messages in KDP. The reps at KDP can't figure out why, but they did say the document needs to be flattened. I "thought" it was flattened when I exported it using Adobe Presets, but the previous versions uploaded fine without being flattened. Has anyone here had success exporting paperback PDFs from InDesign? The book has a lot of photography, so I've been using Press Quality rather than PDF/x-1a, although I did use that setting a few times and still had upload failure. KDP says it will be two days before they get back with an answer, and we have already scheduled the book launch since the book is live with the previous version and we obviously weren't expecting this to happen. Can anyone help me figure out what's going on?
