When i sign in to xbox.com it sends me to "Change your child’s Xbox privacy and online...

I tried that, but every time I try to visit account.xbox.com, it automatically takes me to a page about changing your child's Xbox privacy (https://support.microsoft.com/en-us...ge-childs-xbox-privacy-online-safety-settings)
and so I can't sign in. It even happens when I go to Xbox.com and click on "my account"--I get redirected to the same page. I have no idea why this keeps happening. Also, I can't click on "sign in" on the Xbox website.

Sorry to hear it. Hopefully the info at this link can help you https://support.microsoft.com/en-us/hub/4294457/microsoft-account-help

Remember that if your account is a child account the parent account will need to adjust the permissions.

If you're having trouble changing your privacy and online safety settings on your Xbox One console, check to make sure you've done the following:

• You're signed in to Xbox Live. You must be online and signed in to make changes.
  
• You’re signed in to the console using an adult account. Children and teens are restricted from making changes to their own privacy and online safety settings.
  
• If you receive an error message when you try to change your privacy settings, search for the error using the
  
  Error Code Lookup Tool.

Note If you want to manage your child's privacy settings, see
How a parent can change the privacy and online safety settings for a child account.

Hi nkTJH!

I'm sorry that your experiencing this problem. Sadly, Hassassinade is right. There isn't a way to change the birthdate on the child account once its created. If your having a problem trying to change the privacy and online safety settings on the Xbox One,
try and go throught Xbox.com. When you sign into the parent account, you can go to "My Account" and access your privacy and online safety settings for both the parent and the child account. If that doesn't work then your best bet is to try and contact support
to see if there is additional troubleshooting they can do.

I'm on my only account attached, which it claims to be the child account and Xbox privacy and
online safety settings it just sends me to:
