“How do I check if my Nintendo account is linked to a profile?”
From the home screen click on the profile user name to check which Nintendo account is linked to that profile.
If the user profile page has ‘Link Nintendo Account’, that means a Nintendo Account has not been linked to this user.
If a user profile is linked to a Nintendo Account it would look something like this.
To view the Nintendo account linked to this user profile, go to the left side menu and scroll down to ‘User Settings’. Under Nintendo Account click on ‘Check your Account Information’.
