App Restrictions and Screen Time

Hi there, i’m hoping someone can help me, i have managed to put the screen time on an ipad which i am trying to restrict in the evening to certain hours, however the child who owns this ipad has figured out how to work her way around it and ensure that some apps like social media ones are still available when screen time is on. I’m just really hoping someone can help me with putting the restrictions on these apps. Thank you in advance.
