Kindle for macOS 11

Device:

 MacBook Air (M1, 2020)

macOS Big Sur

Version 11.7.10

Kindle Classic 1.40.3

Bought Hokusai Kindle digital book.

Cannot download the ebook.

System tell me to install a new Kindle for macOS 11 and newer.

Send me on Apple App Store, but the available Kindle program works from macOS 12…

The “old” Kindle Classic works well with ebooks bought before, why is the download blocked ? Updating macOS because of every single program updates brings the risk of blocking many other programs; it is therefore a must, that elder versions remain active.

Now the logical solution would be to re-activate the Kindle working on macOS 11, or to re-activate the function of ebook download only.

Can you help ?
