I have recently purchased a new Kindle Fire (Generation 5 Kindle Fire 10inch)
However when I send books across (using both the usb and the calibre companion app) Sometimes the books vanish, they aren't in the book library. I never had this problem with my last kindle fire (gen 2). This does not always happen sometimes, the books go direct to the library, I have tried using different files both mobi and AZW3 but this does not seem to make a difference??
I can find the files/books in the ES app they are in the document file, I can transfer them into the book file this allows me to access the book after I have opened it via the "recent" page on the home pages of the kindle, but it does not show in the book library on the kindle.
I hope I have made some sense and you can help me on this?
