Canceling Kindle Unlimited can be a bit tricky if you haven't done it before. You typically need to go to the Amazon website, sign in, and navigate to "Accounts & Lists," then "Your Kindle Unlimited." There, you should see an option to manage or cancel your subscription. Have you been enjoying Kindle Unlimited until now, or are you finding it less useful than you expected? It’d be interesting to hear about your experience with it!
