Where's Apple Tv version ? – Amazon Prime Video Review

The app works pretty well on my iPhone 6 running iOS 10 and AirPlay does work to my 4th Gen Apple Tv but there's one thing missing. There's iPhone, iPad, & iPod touch support but no Apple Tv app ? How does that make any sense? Even the PS4 has an Amazon video app. Why do I have to AirPlay from my iPhone to my Apple Tv which wastes my battery charge to watch videos that I should just be able to watch just using my Apple Tv ? We need Apple Tv compatibility!
