@TeamYouTube Suddenly all my YouTube accounts have restricted mode locked. I own all accounts so why am I having restricted mode locked. I don’t have any parental restrictions.
That's odd. It's an optional, opt-in feature that viewers and network admins can turn on if they want a more limited viewing experience on YouTube. Here's more information about the setting: https://goo.gl/zcp9Mv . Let us know if that helps.
