When I try to download the Apple TV app from the amazon cloud, it says it is unavailable. Any tips?

The Fire TV app page for the Apple TV app says it should be available for compatible devices: https://www.amazon.com/Apple-Inc-TV/dp/B07XDD7GYT/ref=sr_1_3

“Fire TV Stick (2nd Gen) and Fire TV Stick 4K customers will be able to download the app starting today in the US, Canada, UK, Germany, France, Italy, Spain and India. Fire TV Basic Edition customers in over 50 countries can also find the Apple TV app in the Amazon Appstore on their Fire TV. The app will be coming soon to Fire TV Cube (1st and 2nd Gen), Fire TV (3rd Gen pendant design), Toshiba and Insignia Fire TV Edition smart TVs, and Nebula sound bar. The Apple TV app is not compatible with Fire TV (1st and 2nd Gen) and Fire TV Stick (1st Gen).”

So it depends on your model Fire TV Stick.

Not according to Apple. I have a brand new toshiba amazon fire 4K tv and the app doesn’t work for it nor is the app or airplay. But my old fire stick tv does work. How I found this out? Apple... Apple is still rolling out applications to support all the products.

If the app says unavailable, it’s not yet available for your model.

I also have the firestick 4k and cannot find the app to even download it.
