You can't directly change a supervised Nintendo Account. Only the parent or guardian who set up the supervision can make changes.
Here's what they need to do:
- Log in to the Nintendo Account: The parent or guardian needs to log in to the Nintendo Account website using their own account credentials.
- Go to the "Family Group" settings: Once logged in, they should navigate to the "Family Group" section of their account settings.
- Locate the supervised account: They will see a list of accounts associated with their Family Group. They need to find the supervised account they want to change.
- Modify the settings: The parent or guardian can now adjust the settings for the supervised account, including changing the parental controls, adding or removing restrictions, and even removing the supervision altogether.
Remember that changing a supervised account requires the parent or guardian to have access to their own Nintendo Account.
