Peacock

I've lost access on my TV to my (free through Xfinity Diamond reward) Peacock Premium. 

I can access on my cellphone, tablet.

But not on TV. On-screen message from Peacock is to subscribe or to login to Xfinity account to activate Peacock. I did that on the web (using cellphone) and it showed as successful. But I still don't have it on TV. 

I did a hard reset, but nothing changed.
