I have a Tivo Roamio Pro and I can access the Xfinity App and search the programming. But when I select a program and click the 'Watch Now' button, it takes me to the cablecard pairing screening. I've tried several times over the past few weeks and it keeps going to the cablecard pairing screen. The Xfinity app had worked in the past but something seems to have happened to it. Any help would be appreciated.
