Question: how to download xfinity app on roku smart tv?
Answer: Activating the Xfinity Stream Beta App on Roku Open the app from the Xfinity Channel in the Roku Channel Store and choose Sign In. You'll see the Activation Code screen on your Roku or Roku-connected device. Go to xfinity.com/authorize from another device (like a mobile phone, tablet or desktop - not from your Roku).
