I am able to easily Airplay from my iPad to my TV. However, when I try to airplay anything from the Stream app, I get an error message that looks like it's a license issue. This makes no sense since I'm in my home and on Xfinity internet service.
I contacted Comcast customer support but didn't get an answer why this is happpening.
adding... currently you can use a modern version of the Roku device and the xfintiy channel to watch your full subscription without a monthly charge for the TV connection.
