You can try running your failed EPUBs though the Check Book function of the calibre ebook editor or EPUBCheck to look for problems. You can also use Amazon's Kindle Previewer to get Amazon-specific error messages. |
Thank you. I tried Kindle Previewer and it turned out the certain problematic epub had a problem with the table of contents. It works on any other reader app I've tried, Amazon is just picky I guess.
This is kinda a headache tho, aside from the missing cover thumbnail, there's a chance that the epub you bought from other sources aren't formatted correctly (at least according to Amazon's standards). Even re-converting the book using Calibre didn't fix it automatically.
Whispersync on sideloaded content is the only thing that made me stay with Kindles. Covers are a pretty big part of that. I'm hoping Amazon would at least update documents to have covers.

Update
I played around with the updated personal documents. Amazon is sending the documents to Kindles as azw3 format now. So we have the enhanced typesetting. That's really the only difference. We can't really take advantage of any of the azw3 features because Amazon doesn't allow metadata on personal documents.
While I'm happy with the options for more fonts, I'd still rather have covers.
