iOS Children's Game: Closing and relaunching again allows user to access the App Store

Hello friends,

I'm making a children's game for iOS and they have understandably strict rules for posting games intended for children. I understand how to setup a Parental Gate and I'll be making my own soon. On the other hand, the section that I highlighted below, I'm unsure of what the tester was referring to and how to fix it.

Is there something I can edit in XCode before archiving the build?

Thank you for your time, -Will
