Hello!
I'm kinda new to Jutoh (and epub publishing as well), but usually along with other tests I do use test via "Send to Kindle" service by Amazon. It's the one that you send an epub file to email and than it appears on your Kindle.
I've tried to make a "test" preview book from docx file and generated epub with a format (style?) epub and Kindle.
I've also processed result files by Calibre, it found some errors, but could open them without issues.
Both files were failed to deliver to Kindle. As Amazon is not providing any error messages, just general "There were a problem..." I'm wondering, is there a recommended set of options to make it work?
Thanks in advance!
