Clear Safari cache on a controlled family account?
I control my son’s under-13 account through family sharing. Safari on his iPad has been infected with the dreaded pop up ad malware, but the option to clear his Safari cache in Settings is grayed out (presumably because of the family sharing thing). I deleted all individual website data but how can I clear his cache and history? I already turned off java as suggested on another thread and that is a temporary fix but I fear it will mess up some of his websites. Thanks.
iPad 2 Wi-Fi, iOS 11.4.1
