Good news! Amazon now has ‘automatic book update’! Opt in for automatic book updates to receive new versions of your books when Amazon confirms that changes (updates, corrections, etc.) have been made. In order to retain your notes, highlights, bookmarks and furthest reading locations, ensure that all your Kindle devices and reading apps have the “Annotation Back Up” setting turned on.
To do this log into Amazon. Go to the drop down menu under “Your Account” and click “Manage Kindle.” This will take you to your Kindle library screen. You should see this near the top of the screen: “Automatic Book Update is now available. Learn more” Click on that and you will be taken to the screen where you can turn on this option.
