"Ask to Buy" feature
Does the "Ask to Buy" feature still work after the child is 13. I would want it to still be enabled until a time I think is appropriate to disable it.

Who can use Ask to Buy
Familes can use Ask to Buy after they set up Family Sharing. The family organizer can turn on Ask to Buy for any family member who isn't an adult. It's on by default for any children under 13. You'll be asked to set up Ask to Buy when you invite anyone under 18 to your family group.1
If a family member turns 18 and the family organizer turns off Ask to Buy, the family organizer can't turn it on again.
