Age rating set as child randomly

I think the closest you get is managing the games by your child's age.

Here is a guide for it:

You can set your child’s age, which Xbox One uses to control the child’s access to specifically rated games, movies, TV shows, and music. By default, if the child is under 8 years of age, Access to content is set to “Off.”

To change the default setting for your child:

1.Scroll left from Home to open the guide.

2.Select Settings.

3.Select All Settings.

4.Under Account, select Family.

5.Select the child account you want to update.

6.Select Access to content.

7.The content limits are unrestricted for all users over the age of 8. You can select preset age-appropriate limits by choosing your child’s age from the list. We’ll show you what the presets are for that age. You're not restricted by date of birth—you decide
which maturity level is appropriate.

Hi there

Child accounts are set to age settings for the region you cannot really change the age, But through family settings your parent or guardian can set it up but please be aware there is of course restrictions depending on where they broadcast.

Example mixer does have an age setting for age here is a link about that information. https://watchbeam.zendesk.com/hc/en...scussion-Channel-Ratings-and-Age-Restrictions

Hello,

It's not possible to convert a child account to an adult account before the age of 18. The settings you're changing are privacy and online settings. Titles that are marked as Not Rated or M (mature) cannot be purchased by the child. You can purchase them on
an adult account on the same Xbox 360 console and the child will have access to that content as well on that same console.

Hello,

If you are attempting to download the Medal of Honor Warfighter Beta Demo then there is no way to download that unless your account is
over the age of 18.

For Demo's regardless of parental settings or ratings allowed M (Mature) and RP (Rating Pending) content cannot be downloaded on Child or Minor accounts.

You would need to make an account over the age of 18+ with a gold membership in order to download the beta. Once the beta is downloaded, you should be able to play the beta on your child account as long as your over
the age of 13.
