@Bluesriff7 , it looks like parental control is set to age limited.

You can change this yourself if on contract by going to the app and clicking on the icon at the top right and then clicking on settings and permissions and then manage settings, scroll down to where it says parental control and change it.

If on pay as you go, you would have to ring customer service and pay a refundable amount with a credit card to get it lifted, or go to an EE store with photo ID.
