Hi! I have Kindle Paperwhite 2012, also have epub and mobi versions of my books. Usually I send books to Kindle via email to be able to read them with my phone too with Whispersync working.
When I'm sending just epub or mobi versions via email - covers are empty. Same is when I convert to mobi BOTH in Calibre. Also cover is displaying on my phone when I'm downloading these versions from the cloud, so cover itself is there. If I convert to mobi OLD then cover is displaying on Kindle too but word wrapping is broken (and publisher font is gone, as I understand due to OLD version of mobi or some compression during conversion) and text starts looking much much worse since it's in Russian and word wrapping is highly desirable there.
So is it possible to make covers visible on Kindle, have cloud sync and not to break word-wrapping at the same time?
