Apple Fitness + won’t connect

I cannot connect to Apple Fitness + on my iPhone or iPad. I have a shared family subscription which is showing in my Shared Subscriptions. I have the latest version of IOS on my iPhone, iPad and Apple Watch. I have unpaired and repaired my watch with my iPhone. I’ve restarted all my appliances multiple times, used different Wi-Fi routers, used 5G and I still get he same screens. I get a “try it” green button (I never had that before) and when I press it I get a “cannot connect” screen! Can anyone help me please?
