I have the exact same issue. The xfinity Stream app on all my Roku devices and tablets will not stream anything other than the major local networks. Every other channel says a subscription is required and an upgrade is needed. I spent over an hour chatting with an agent restarting, reinstalling, reauthorizing everywhere. Nothing worked. Very frustrated to pay for services that I can not use.
Having the same issue starting Friday 11/20/2020. I was on hold for the 2nd tier Tech Support for almost an hour wait (twice!) to be told that they are aware of the this problem and the the engineers are working on it! YES the first tier tech support could not tell me that! had to wait for an hour for the 2nd Tier Support to tell me that.
Anyways, one user reported that remove and re-install the app solved the problem. Anyone else had luch with this?
I am having the same problem with all of my Roku Sticks. The channels had been working up until sometime in the last 24 hours.
I have tried restarting my modem, restarting my Roku Sticks, and uninstall/reinstall Xfinity beta app. The problem has persisted.
only a temporary fix. on nbcsports it works for a few minutes then the "subscription" error message pops up again.. usually when my team is about to score a goal! lol
