What Changed
Amazon's newest Fire TV Sticks run a brand-new operating system called Vega OS. This replaces Fire OS, the platform your current Fire TV app was built for.
Because the app was built for Fire OS, it isn't compatible with Vega OS devices at this time.
This is an industry-wide shift, not something specific to Uscreen, so all streaming apps need to be rebuilt or updated to support Vega OS.
đĄ TIP: Your existing Fire TV app continues to work normally on all Fire OS-based devices. Only the newest Vega OS models are affected.
Which Devices Are Affected
The following Fire TV devices run Vega OS and are not currently supported:
Fire TV Stick 4K Select (2025)
Fire TV Stick HD (2026)
These Fire TV devices continue to work with your app:

Fire TV Stick 4K Plus
Fire TV Cube
Other Fire TV devices running updated FireOS
