Would like feedback if possible. We have a current Fire TV app that was built with the app builder. The App builder design template that was created 3+ years ago is getting "stale" and with the great "UX/ UI eye candy" that users see and experience with platforms like Hulu and Disney Plus among others, the app builder template is looking very "old school".
How much flexibility do we have with in enhancing the UX/ UI using the Android Leanback or other Android APIs with the existing Fire TV App builder created app? Because from a pure functionality standpoint we are happy with where we are with our current fire tv app builder core app (other than it has a very large code base) including features like "continue watching" and the rest of the media player.
Alternatively we would need to rebuild from scratch which would be a huge undertaking.
