Parent permission for a child account not working

I bought a new xbox console. Logged in with my parent email. I then tried to add my 7 year old son. I get all the way to a point where i get an email to give him permission. When i click through and sign-in i get a message "something went wrong. It's not you, its us". That's it. This has been going on for one week now. Very frustrating for my son since he can't play through his own account. I let him play a little from my account but that's unsafe. Help please!
