I just got off the phone with Comcast/Xfinity tech support. We were discussing why you cannot use the streaming utility to watch TV or access your DVR with the Brave browser.
This person told me that Comcast only allows content to be streamed to “approved” browsers and that they block Brave users. The only approved browsers at this time are Safari, Firefox, and Chrome. While they said they are looking into adding Brave to allowed browsers in the future I have no idea how long this will take.
I know a lot of people have had this concern and I hope this sheds some light on the issue.
