If you were in a family group listed as a child account the adult of that group still has to change your privacy settings

Hi Momcilo, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

If you're still a minor, I'm sorry but an adult is required to manage your privacy and online safety settings.

To fix this, you need to ask an adult to add you as a member under their family group (https://account.microsoft.com/family) and once you're added as a member, the organizer/adult will sign in to https://account.xbox.com/settings and manage your privacy settings from there.

They will be needing to allow the setting in this screenshot:

I am having the exact same issue. I am an adult, but as I am the only member of the family group I am not allowed to leave it. It prevents me from playing multiplayer Minecraft with my family, and the only way to get out of that is by leaving the family group which I cannot do. Is there a way around this?

For some reason i cannot change my privacy settings on my main account. I have checked my family settings and it says i am not part of a family to my knowledge.

But also whenever i click on my privacy settings for my xbox it takes me to this page instead: https://support.microsoft.com/en-gb/help/4026796/microsoft-account-change-childs-xbox-privacy-online-safety-settings

I am never able to change my settings PLEASE HELP
