I subscribed to the bundle through SHOWTIME prior to 8/31/22. How can I make changes to my subscription?

Subscribers who started their bundle subscription through SHOWTIME are no longer able to change billing plans (Monthly to Annual billing or Annual to Monthly billing), or switch between the Essential and Premium plans. If you currently subscribe to the bundle through SHOWTIME, and want would like to make any of these changes, you will need to cancel your current bundle subscription and then resubscribe to the Paramount+ with SHOWTIME bundle through the Paramount+ app or website. Free Trials are available to new Paramount+ customers only.
