Xfinity Stream Issue = Paramount+ With Showtime - Billions - Season 7 - Ending Of Multiple Episodes Cut Off / End Early

We are watching the Paramount+ With Showtime television show Billions, Season 7 on Xfinity Stream - and several episodes cut off many minutes (probably at least 10-20 minutes) before the ending.  Thus far, this includes Billions Season 7, Episodes 1; 5; and 7.  We have been trying to connect with Xfinity Customer Service to see if this issue could please be fixed, but have had no luck making contact despite numerous tries.  Any chance the entire Episode for all the Season 7 Episodes of Billions could please be posted to the Paramount+ With Showtime Xfinity Stream site (https://www.xfinity.com/stream/entity/8757384295010924112)?  Thank you!
