Apple TV subscription not working

I am subscribed to Apple TV. It was working a week ago, now it’s not.

I am signed in on my phone and on my FireTV. Last week I watched Physical on my FireTV. This week I tried to watch a show and both on my phone and on the TV I just get the “How to Watch”. When I “manage my subscriptions” it shows an active subscription set to auto-renew on March 22 (two weeks in the future).

How can I fix this?
