Peacock Premium

I have activated my Peacock Premium subscription.  I can stream Peacock on my computer.  However, I can not access Peacock via my TV using the xfinity cable service.  Currently I can speak "login to Peacock" via my voice remote. On the refreshed screen I choose to subscribe to Peacock Premium and am then directed to a login screen which already has my xfinity email address shown.  However, the screen locks up at this point and I am unable to enter my xfinity password or proceed with any other activity.

What more do I need to do to gain access to Peacock on my cable TV?
