Epub publishing to Kindle is not.... really working

[FrameMaker-dk]

I am working with a client who has a number of guide books he wants to submit to KDP publishing. I have been investigating the proofing options now and has to conclude, that while one can generate an epub file which will look right in Calibre and on some epub readers, it won't work for Amazon.

FrameMaker 2022 ships with an outdated script for Amazon and the epub which is generated from FrameMaker won't be validated by Amazons KDP previewer.

Anybody from Adobe here, who can answer whether there are any attempts at fixing these issues?

I'd go straight to the source and contact the FM folks - see https://helpx.adobe.com/contact/enterprise-support.other.html#framemaker for your Adobe Support options. I'd recommend using the tcssup@adobe.com e-mail address as it reaches a team dedicated to Technical Communication Suite products including FrameMaker.
