My Appletv subscription ended a month early on Roku. Apple support was not able to tell me how to re-enter my apple id on Roku to sign in again. How do I do it?
I don't think your apple id will work to sign into Roku. You should be able to sign into your Roku account using your email address and password. Once you are logged into your Roku account check your subscriptions and purchases. If you purchased Apple TV from Roku it will appear on your Roku account.
