For those who have trouble with the upgrade. Also, I was asked for an update, and thereby redirected to Amazon.com !? I then the app on my Fire HD uninstalled, cleared in my account and then can easily deliver via Amazon.com again. After a successful installation on the Kindle started and "lo and behold" it went with my old score, as usual !!! So do not always call the same for help, but even try something once or risk !!!
