I am trying to access Apple TV on a TV using Apple TV at this location for the first time in six months. How can I sign in? It wants me to start a subscription, but I already subscribe.

Do you have the Apple TV app on your smart TV or third party streaming device,

or do you have the Apple TV box? If so, which model?

To sign in to the Apple TV app on your smart TV or third party streaming device, go to the in-app Settings (sprockets wheel icon) and then go to Account. Sign in with the account that has the subscription.

To sign in to the Apple TV box, go to Settings﹥Accounts, and enter the account that has the subscription.
