As a Kindle user, I still miss the old version of the site. The new one looks great on normal desktop, but the old one was simple enough to load and directly download books on the device's built-in browser.
Is that a Kindle issue?
You can download books in most browsers. I know Amazon have done things to make life difficult for other stores in the past.
That's interesting. What about the new design prevents you from doing it? Genuinely asking here. We may fix it if it's actionable
