New credit card and multiple Apple TV's

[AlphaTeam]

I have multiple Apple TV's at multiple houses and just got a new CC. Do I have to update my credit card on every Apple TV, or if I do it on one, will it replicate to the others?

IIRC, it uses the card tied to your appleID. Just update the card on your account and it should update everywhere.
