I submitted a BBB complaint two weeks ago and they did not even respond. Comcast contacted me a few days later and said they are waiting for a firmware fix from Roku.
I heard the same from Comcast after going through their "executive" escalation.
The automatons who answer the phones there are US based and have authority to do more than send a "signal" to a Comcast cable box that doesn't exist (in this case since we are using Roku boxes).
However, we may be in for a longer wait. Roku typically updates its Linux-based software twice a year with one or two bug releases shortly after the main release.
In this case, though, the xfinity stream app worked flawlessly until it changed from a beta status (where it was for several years) until the beta disappeared about a year or so ago.
Roku closed the thread regarding this issue as it was pertaining to the previous operating system. The problems are still the same.
