I just bought a brand new Chromecast and set it all up under my main email, and it automatically added my YouTube account connected to that email. I want to add a new YouTube account to it, since my account with the premium membership is under an older account. Unfortunately, clicking on my profile photo gives me 2 options: switching accounts (which only allows me to go to my main email's acc) and signing out (and when trying to sign in, prompts me again to "choose an account" and only allows me to choose the main email's acc).
I'm unsure if I'm just purely missing something here or if it's a bug. Any help is greatly appreciated and welcome!
Thanks for reaching out. To confirm, is your old email already added on your Chromecast with Google TV? If not yet, please add that account. Check the steps below:
Tip: On the Google TV home screen, the customer will only find recorded and recommended content for the primary account.
Important: To use multiple accounts in the YouTube or YouTube TV app, you need to sign out of one user’s account and then sign in with a different account.
