why is my account age restricted when i changed my name

never mind i fixed it if you are playing on PC, go to the Xbox app in the Windows search bar right-click, then go to app settings, then click on repair and reset app, and that should fix it.

Thank you so much for the response. If that is the case then why was I able to download DESTROY ALL HUMANS, with it also having an age restriction of +16? Also how do I check my age restrictions? My Microsoft account also shows that my age is well over 16 years, unless my Microsoft account is separate from my Xbox account

I am 13-17, and I want to change my Xbox name and profile image, is there any way to do that by bypassing the age restrictions?

Try clicking on the my account link at the top right of most any page. This will take you to several options and you should be able to navigate to the area you need from there. You can change just about everything by updating your account. There could possibly
be a problem changing your name as this might look as though you have given your account to another person. If this ends up being the case you will have to call phone support at 800-4MY-XBOX for the US and Canada.

The birthdate that you entered when you created the account will never change. If you entered the wrong date, then you are out of luck unless you create a new account.
