How to change child account to an adult account

I can't remember 100% but I am sure whoever set up the child account can change it. Like if you made an adult account on the xbox before making the child account that adult account can change wether the child account is a child account or and adult one.
I will just test this out myself now and post how it went

As said there is no way to change your child's account to an adult account until the age of birth you have put has reached the age of an Adult for your specific region. There are some troubleshooting tips that if your account is past the birthday and still
a child's account there is a way to promote to an adult account.

Heya!

To be sure your account was set as an adult account sign into your Microsoft account and post
a photo of what you see under family.

Keep in mind that changing the date of your account does not change how old the account is and accounts automatically switch from child to adult at the correct age.
