Update: I updated to DVR Server 2021.03.18.0114 and Chrome 89.0.4389.90, but now I have another password reset screen from Xfinity. I really only need Xfinity for regional sports networks (NBC Sports local sports channels), so it'd be great if the TVE workflow could just authenticate specific channels for certain sources. Maybe that'd be a way around the multiple authentications that Xfinity doesn't seem to like, especially when the authentications are off the "main" Xfinity home IP / Xfinity Internet gateway router. I hope you all can consider any updates to the add source workflow to try to make Xfinity TVE work (eg, using a TVE source to only add a certain set of channels).
