I'm getting an error message that I need permission from my parent or guardian to make a purchase, but I'm an adult

If you're an adult player and you're getting a message that you need permission from a parent or guardian to make a purchase, try adjusting the parental controls on your account: How can I change my Parental Controls Settings?

If your parental controls are set to the highest preference, try changing them to something else and then back to the highest option to reset them.
