macOS, iPadOS TV app and subscriptions

The Apple TV app on macOS wants me to subscribe or try a free trial for services I have already subscribed to through my Apple TV, like HBO and Acorn TV. My Google-fu is failing me as to a solution.

Pearls of wisdom appreciated.

Have you loggedf in?

Yes. My Apple ID is shown in the Account, and I can view my account info.
After entering my password to view account info, I go back to TV Shows, search for Doc Martin, and have the Try Acorn TV button still there.
