I have been using a Roku 3 to stream xfinity on my TV. I have never had “the box” connected. I can stream live and on demand using the Roku with the exception of 2 programs: 48 hrs and Dateline. When I try to watch these programs on demand I get kicked out of the xfinity app. I can watch them on my ipad and laptop though. All apps and devices updated and restarted.
Any ideas?
