Hmm? Try signing up then with a different e-mail address than the one it shows is active. See if that works. Also, I'd contact YouTube Red to make sure you're not being charged anything if it's showing you've already signed up.
Yes, I did. They were just getting me into a billing cycle and I told them I never signed up. They removed me from their subscription
Good deal! Glad you were able to cancel before they charged you. You might be able to try signing up again for free under a new e-mail address. Then you can watch the show and then cancel before the 30 days are up.
