activated free 1-year appleTV+ subscription, but iphone fails to recognize it

I activated free 1-year appleTV+ subscription, but both of my iphone and fireTV stick fails to recognize it. When I play anyone appleTV+ content, the app asked me to pay.

In contrast, tv.apple.com recognize my subscription and I am able to play for appleTV+ content there.

How to fix it in iphone?
