I got a new Fire Stick yesterday. I accessed the NBCSports app (and the Watch ESPN app). I attempted to sign in using the activation code that each app provided me. I put in my Comcast username and password on each website with my phone and get the acceptance from Xfinity but the apps never started working. It is almost like the Xfinity site did not communicate the acceptance to the Watch ESPN and NBCSports app. Please advise.
