Thank you for asking. The kindle cloud reader doesn't support the offline reading. Therefore, your kindle cloud reader cannot be downloaded via kindle cloud reader.
It is out of our control. If you can download kindle cloud reader, then epubor kcr converter can still handle them.
Anyway, we are sincerely sorry for this issue.Also, we offer  the some workaround. Please contact support@epubor.com to get further assistance.

Hello, this is the second message I placed, the first one was not published and I did not understand why. I ask you if you can fix the link at the top - use KCR Converter to convert Kindle cloud reader to epub/azw3/mobi - because it doesn't work and I don't know how to proceed since my Mac system already updated to Catalina but I never use Epubor Ultimate before. Thanks

Thank you for using our software. The KCR CONVERTER only handles the kindle cloud reader books. But now there kindle cloud reader books cannot be downloaded any more. This is decided by Amazon. So no, kcr converter doesn't work any more.
We are sincerely sorry for the inconvenience caused.

I have Big Sur and while it did take me a while to navigate through all the help files and decipher the best way to pull off converting these files it did end up working. Using the sudo command in terminal and then downloading again made it possible. Thank you. I appreciate the hard work you guys put into this as I know it is hard to write support for so many different variables. A+ to you and your team.
