Peacock No Longer Free?

I have greatly utilized my free Peacock subscription I received since becoming an Xfinity internet subscriber. I even used it yesterday. Today I opened the Peacock app and tried to click on the Notre Dame game— it said subscription needed! But I watched Notre Dame on here two weeks ago! Then I tried clicking on other shows and it told me the same thing! I logged out, then logged back in with the Comcast email I used to sign-up for Peacock. It still doesn’t work. Can someone please help me?! It was a huge perk to me signing up with Xfinity!
