Unfortunately, we don’t specifically support Amazon Firestick at this time. However, members using the Firestick have been able to cast from our App by first downloading an app called Airstream onto their Firestick.
If casting from a PC to a Smart TV with a Firestick, users must first power on the TV before initiating casting from Chrome. If the TV remains off, the casting icon will not appear, preventing casting to the device.
