The kindle cloud reader has removed the cloud and download tabs. But when you open the book, a downloading progress will show at the bottom-right corner. Please just keep this book open until it has downloaded successfully. Then run Epubor kcr Converter to remove DRM and convert kindle books to drm free files.

While the automatic download with the new Kindle Cloud Reader worked yesterday as described, it does not today. Whatever I do and even with a long waiting time, the download does not start.
No message shown, just not starting the download. I'm using Macbook Catalina 10.15.6 with Chrome 84.0.4147.105 and Cloud Reader PlugIn.

Thank you for asking. This is a kindle app bug. You can close this kindle for pc and try to register again. This issue should be fixed at then. Also your kindle app may be registered successfully already.

No matter which way you are using, this is the right steps. Yes, the trial version only converts 20% content of each book. To obtain the whole content, please use the licensed version.
If you prefer something free, please try Calibre.
