I am attempting to self publish in Amazon KDP.(electronic and paperback formats of my novel). I had previously enlisted the help of a book designer who did an excellent job of designing the cover art and formatting text.etc. But now due to circumstances , she is no longer free to assist. And while I have successfully uploaded a PDF document for the paperback book, problems remain in all four areas--issues in responding with accept or deny to proofreaders suggestions and in incorporating these changes into the uploaded document, issues involving uploading the electronic content in UTUB (as Amamzon spwcifiwa), and issues in correctly formatting the cover files, etc.
