Can't add 3rd TV to X1 using the Beta app
I have the gigabit router, and all New Samsung TV's. I have loaded and am using the Beta Streaming app on 2 of the TV's. My 3rd TV just shows a large question mark and various web pages to look at for info to learn more about th Beta Stream. I am using wifi via the Xfinity pods and I have strong signals. I can get YouTube TV (which I am cancelling) and various other channels. I just can't get the streaming app on my TV to open.
Any help is greatly apperciated!
