How do I add a profile to my YouTube TV account?

To add a profile to your YouTube TV account, you first need to sign in to YouTube TV using a web browser or through the app on a mobile device. Once signed in, click on your avatar in the top-right corner of the screen, and then select "Settings" from the dropdown menu. Navigate to the "Family sharing" option and follow the prompts to set up family sharing if you haven't done so already. After setting up family sharing, you can invite family members by entering their email addresses or by sending them an invitation link. When they accept the invitation and sign in with their Google Account, they will have their own personalized YouTube TV profile that allows them to access live TV, preferences, and recommendations separate from other profiles.
