Screen Time On But History Can be deleted

Help! I have screen time enabled for 4 family members. I have limit adult websites turned ON. Yes this allows u to now clear history. BUT - there’s a loophole. If you go into the bookmarks history and tabs section, you can swipe and delete any and all history.

to test this - type a website in of your choice. All of the websites that come up can swipe and be deleted. And it leaves NO trace in screen time.

so, technically history can still be deleted this way! Please help me figure out if there’s an extension I can add. Or some type of option where my family members can not do this
