Hi everyone,

I have been searching on google and forums on this with no clue with this 'simple' problem. Apologize for newbie questions as I am still new to kindle PW3.

I have book collection in ePub, I used callibre (in OSX) to convert into mobi and azw3 and sideload them from Calibre to Kindle. However their covers sometimes show up correctly but sometimes not show up in my kindle.

I did hard reset last night and sideload all the azw3 books (the same azw3 books) right away after the reset, and surprisingly, all of them are worked fine. However, I don't think that this is the solution as the process is tedious as well.

Is there any tips or workflow for this ePub to Kindle conversion process which guarantee for success?

Thank you very much.
