"Apple TV free for everyone December 22 - 25" But HOW to get it? No path seems to be available, only 7 day free trial.

What would be the point of offering "Apple TV+ free for everyone December 22-25" if there is no way to get it, even once logged in with my Apple ID? You can see this exact text on the opening screen of Apple TV+, but it is not a clickable link, and there is no avenue that I can find to access Apple TV+ without doing the standard 7 day free trial. Why say "Apple TV+ free for everyone December 22-25"? Is it just going to be available later today? Anyone?
