I just wanted to put a quick note out about watching
Disney+ streaming using the Fire stick 4k: You can put the app on just fine, however... if you're using a VPN Disney+ may not work. I kept getting the message "Error 73- Disney+ is not available in all areas" when launching the app and I tried to get chat help on their site. The wait time was over 30 minutes so I searched the error message myself on the site and found that if you are using a VPN the app may not work with it. I turned off my VPN and it worked just fine.
