Everything is fine on any "basic" ePub reader (including ADE) and Apple Books, but when we sideload ePub3 files on our Kindle readers, all the custom fonts we use are completely missing.

Please note that if we convert the ePub3 files to .mobi using Kindle Previewer 3.70 and copy them to the same readers, all the custom fonts show up. So, there seems to be something "filtering" these fonts.

We have tried everything and of course all the ePub3 and CSS validations passed with flying colours, but basically now we are stuck because we don't know how to get a Kindle reader to properly display an ePub3 with embedded fonts.

Any help or suggestion would be greatly appreciated!

Thanks.
Mobi does not handle embedded fonts. So that's not going to work. Create KF8 format eBooks. They do support embedded fonts.

But the problem with a Kindle is that they do not display embedded fonts by default. You have to go to the Aa menu and select Publisher Font. Many won't do that. So your best to not embed fonts and make your eBooks work with a Kindle using KF8 without embedded fonts.
