Greeting Gator4814,
Welcome to the Roku Community.
Even though the terms “casting” and “screen mirroring” are commonly interchanged in the industry, there are differences when using them with your Roku device. To use casting, the supported app must be installed on both your mobile device and your Roku streaming device.
Since the channel is not available on the Roku device, we suggest you screen mirror your Windows device. To learn more about replicating the screen from your compatible mobile device on your TV, review the detailed article about screen mirroring.
Hope this helps. Keep us posted.
Regards,
Nimfa
