TV Listings

Yes, I am a dinosaur.   I watch TV on a television set.  I (used) to check the Xfinity listings on my PC.  But for the last week, I click the Xfinity Stream  and instead of being given the option to see the TV listings, all I can access is " Xfinity.com/stream/purchases".   Typing in "listings" instead of "purchases"   at the end of the URL still takes me to the "Purchases"   page.
