I thought the idea was that i could go into the Apple TV settings app and sign in with my TV provider, so that I would not need to sign into into apps individually.
What i find is that even after an app asks for permission to access my TV subscription, I am still required to go to another device, navigate to a URL, and sign in with my TV provider password.
Is this working right?

According to Apple, not all providers or apps support single sign-on. As you've already discovered, sometimes you need to sign-in to an app separately. This isn't just with Apple TV; I have a Roku and it does the same thing.
Normally, I would paste the names of the TV providers and apps that support SSO. However, this list is very long and often changes so posting them here doesn't make sense. Instead, I'll post the links to Apple's site that contain the lists. That way, it should always be up-to-date.
