Windows 10: Error adding child to family

Trying to add a child to my family group. After going through and giving consent, I get this error screen. MS support has told me there's nothing they can do about it and they referred me here. Is anyone able to help with this?

Problems adding a child on the family account

Hi,

After your child accepted the invitation, did you have him/her sign in to Windows 10 using the same email address you sent the invitation to?

That will be the last step in adding your child to your family.

Family Safety - add device to child profile

Since this is the case and you have ensured the settings are correctly setup in family Safety, we suggest that you sign in using your main account and remove you child's account from Family Safety list. (Refer to the image below for reference.)





After completing the steps, attempt to use the email address of your child to login to the computer and see if the same error message still shows up. If the error no longer shows up, we suggest that you attempt to add the account back then to Family safety.

Regards.
