I am new to using Kindle Direct Publishing and I have uploaded one book recently, with pictures, and it converted nicely into a mobi file and uploaded to Amazon Kindle without issue. I figured out how to convert the Word file into html filtered, compress together and upload.
However, my second book won't upload on Amazon as a mobi in the bookshelf. Instead it uploads as a 'application/octet-stream'? When I try to view the document on Amazon's Kindle Previewer application, it gives an error - yet the Bookshelf tells me it uploaded successfully. I find this confusing - especially since this second book is all text and no pictures.
Is a 'application/octet-stream' ok for upload or am I doing something wrong and it should have uploaded like a mobi file like my first book. I followed the same steps as my first book but the upload result is always different. Any help is greatly appreciated.
