Xfinity fail with Roku

Three or so weeks ago my Xfinity stopped working on my Roku platform. My two other TVs in the house with a Xfinity box work, over my 4 other TVs with Roku all have the same issue. Clearly this an Xfinity issues and dispite what they have reported on this platform it us a widespread problem. I've been looking for a good reason to dump Xfinity...We pay +$400/month. If this isn't resolved this week we'll need to partner eith a more reliable company.
