AMAZON KINDLE

If you’d like to receive updates to your Kindle books automatically, you can turn on automatic updates for your books from the Manage Your Content and Devices page.

Before you enable the Automatic Book Update feature, make sure to turn on the Annotations Backup for your Kindle device or Kindle reading app to sync your notes, highlights, bookmarks, and furthest page read. The following devices automatically enable the Annotations Backup:  Kindle Fire HD, Kindle Fire HDX, Kindle for Android, Kindle for Windows 8, and Kindle for BlackBerry 10.  As a result, you cannot turn off the Annotations Backup. Follow these steps to enable the Automatic Book Update:

1. Visit the Manage Your Content and Devices page
2. Select “Automatic Book Update” from the left navigation bar.
3. Click Turn On.
