Having problems getting the latest updates on your Kindle?
It’s come to my attention that Kindle doesn’t always download the latest version of the book. To fix this:
Go to http://amzn.to/2l53jdg
Quick Solutions (on the left) select
Digital Purchases. Search for your purchase of Docker Deep Dive kindle edition and select
Content and Devices. Your purchase should show up in the list with a button that says “Update Available”. Click that button. Delete your old version on your Kindle and download the new one.
If this doesn’t work, contact Kindle support and they’ll resolve the issue for you. https://kdp.amazon.com/en_US/self-publishing/contact-us/.
