Showtime anytime via Roku Express

Validating that I have subscribed to Showtime via Xfinity is failing on my Roku Express.  The Xfinity website has changed a lot recently and I'm wondering if there isn't something broken now.  I do the following when accessing Showtime via Roku. I get  a message asking me to verify a subscription by providing a 5 character code that I'm supposed to log on to showtimeanytime.com/activate, present the 5 char code, then I choose my provider (Xfinity), then it takes me to an Xfinity logon.  After successful logon, I'm supposed to get a Success on my TV.  But it is not happening now.
