The Google Play Store listing of Amazon Prime Video app was earlier only exclusive to NVIDIA Shield TV as part of a limited-time licensing deal. And now the app is available for all Android TV devices. It might be possible the app is not yet listed on your Android TV device and at the time of writing, we couldn’t find the app on Play store for Android TV. It’s possible that the app went live a little prematurely, or that there’s an issue with the device compatibility list.
The existence of Prime Video for Android TV on the Play Store is a step in the right direction. The move comes shortly after the retailer decided to start selling Google Chromecast and Apple TV. While the things have started to ease up a bit, but Amazon has yet to bring Chromecast support to its Prime Video apps for Android and iOS devices.
