Paramount+ App for Showtime subscribers

When will Xfinity allow Paramount+ with Showtime subscribers to use their account to access the Paramount+ app? Xfinity made a deal with Paramount that allows this but hasn't given us access yet.

I understand some Paramount+ content can be viewed on the Xfinity Stream app or On Demand but it's not the same and some shows are missing. Most other major cable & satellite providers allow this, including Spectrum and DIRECTV, see the list here: https://www.paramountplus.com/partner/

When will Xfinity be added, it's been months?
