Which play settings are you seeking to change?

Hello, PsychPerspicacity. Thanks for reaching out. I'm Lucas, an Independent Advisor and a Microsoft user just like you. I'll be glad to help you out.

Unfortunately, child accounts cannot change their Xbox profile privacy settings. Doesn't matter if they are on a family group or not.

If you need to change your privacy settings, you will need to ask a parent to create a family group, invite you to the group as a member and change your privacy settings for you (if you are not on a family group).

You can check if you are on a family group by going to https://family.microsoft.com and see if it shows only your account or other accounts too.

For a detailed tutorial on how a parent can create a family group and change your privacy settings, please refer to:

But are you sure you cannot play online because or your privacy settings? Would you please share a screenshot of the message you receive when trying to play online?

Feel free to ask back any questions you might have. Waiting for your kind reply.
