AirPlay not connecting to Fire TV

Fire TV Stick is a streaming device that plugs into your TV's HDMI port, allowing you to access streaming platforms like Netflix, Hulu, and Prime Video. It does not natively support AirPlay, which is Apple's wireless streaming technology.

• Your TV must be AirPlay-compatible or you need a third-party device (like an Apple TV) that supports AirPlay.
