Over 18 but My account believes it to be a child account

Hi, 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.

This may mean that there is an organizer account linked to yours. Please sign in to https://account.microsoft.com/family and check if you're a member of a family and is added as a "member".

Over 18, it's not a child account

I am older than 18, but I don't believe that's the problem since the other accounts on my Xbox including the child accounts can broadcast.

There is two ways that MS sees an account as a child account.

1. The DOB when the account was originally setup. (which is set in stone and can not be changed) If the DOB is under 18 it will ALWAYS have to be in a family as a child account till it reaches its 18th birthday.

2. If the account is in a family as a child account. (even if the DOB is over 18 if it is still in a family as a child MS will see it as a child)

With that being said

When you say it was set as an adult account since then do you mean in the privacy settings on your xbox?

This is not going to change it to an adult account. even if the DOB is over 18

So if the DOB is over 18 this is what you need to do.

Sign in at account.microsoft.com/family with the parent account and remove yourself from the family this will then put you into your own family as an adult.

Keep in mind if you do this and the DOB when your account was originally setup is still under 18 you will NOT be ABLE to do ANYTHING on your account till you are added to an account as a child account.

In the family, my account is certainly set as an adult. And my DOB was not changed in the privacy settings. I’m talking about the DOB at account.Microsoft.com.

Since you're on a child account, you will have to make the purchase on a 360 console.

If the age of your account is 18 or over, you would want to look into promotion your account to an adult account. If it's under 18, you would still be considered to be a child account.
