When I use calibre to convert some epub files into both Mobi filetypes and send it to kindle via email, I receive azw instead of azw3 on the device. When the same file is converted to mobi file using kindlegen, I receive azw3 correctly.
This problem only occurs in a small part of epub files, and there is no warning message when using kindlegen to generate mobi files.
Why does this happen?
