Privacy and online safety settings not working

I am trying to change a child account online settings via my adult account that is part of the same xbox family, this is to let the child account play online etc. I can change some privacy settings but not the xbox one/windows 10 online safety settings.
when I tick to allow the 'Join multiplayer games' setting and then click submit it just resets it back.

if you want to find out what settings I am trying to change, go to the xbox live site, sign in and go to xbox settings. on the left should be a button that says 'privacy and online safety' then click 'xbox one/windows 10 online safety settings'

any help would be appreciated

:)

 

HELP!

Check your Online Privacy Settings .. click customize and look through there .. here is a link with steps on how to get to the Online Safety and Privacy Settings: support.xbox.com/.../online-safety

Check your privacy and online safety settings:

support.xbox.com/.../manage-privacy-safety-online

 

If you are indeed on the adult account in the family you should be able to change that setting with no problem.

I would suggest another browser.

On your adult account go here
https://account.xbox.com/Settings and click on the child's account and allow the option on the first page called "Share stuff people make (Xbox 360: Member Content)" to everyone (must be everyone). Also, on the first page, "Others can communicate with voice,
text, or invites" to Friends or Everybody. And on the xbox one/windows 10 tab the second option down, "Join multiplayer games", enable that. And then log out and in on the account in question on the console/device and that account can play online.

If it still does not work on multiple browsers please contact xbox support in a live chat here:

thanks for the response but this is just telling me what I'm already trying to do, when I change those settings and click 'submit' it just reverts to what they where before

 

Then please contact xbox support:

You may be on an account that has the microsoft account an adult but the xbox part is a child. The xbox date of birth can not be changed in any way.
