trouble accessing Apple TV using your streamsaver deal

I signed up for your streamsaver and want to access Apple TV on my television. When I click on the Apple TV+ icon, it eventually brings up a Url code. I clicked on that, and eventually got the message that I had an active subscription through Xfinity streamsaver. But when I go back and try to access Apple TV it brings me to screen that offers me a one week free trial - as if I don't already have a subscription. Please advise!
