We would need to review your controls area to ensure the settings allow for the content you would like your children to view.
Within the Family Zone Portal, if you access Cyber Safety on the left hand side, then Controls and Categories. Choose your childs' age profile and view what is blocked and allowed through here. Every website and app come under a specific category, which you can search for under our research tab. Games will also be listed in here, and you can choose what time period to allow access to games.
Hope this helps.
