Currently, we do not support logging into the live classes on the Fire TV.
To stream, you must join the class from your Android phone or tablet and then screen mirror it to the Fire TV. Using this method, you can leverage the big screen and use your phone more like a tool to receive real-time feedback from your trainer by turning on your camera or entering your reps.
Fire TV does not currently support screen mirroring on iOS and macOS devices. For more information, please visit Amazon’s Fire TV Help and Support page.
