I'm trying to watch the debate I cannot get CNN online. I'm logged into my account. The page shows the line below and a button asking me to buy the subscription. I have logged out and then back in. I tried several other "free" channels and get the same results. Has Comcast changed this service from free to must buy? Incidentally, when I click on BUY THIS SUBSCRIPTION NOW, it leads me to the to a page where I can upgrade to other bundles. Nothing is said about buying a subscription for CNN (or any other channel.) What gives, Comcast?
