I am sorry to hear about the situation that is happening on your son's device.
Kindly be informed that we are not the developers of the Family Link application and it's best to contact Google in regards to this as they are the designers.
Additionally, I will attach the factory reset steps: https://uk.community.huawei.com/ask-a-question-faq-s-3/having-problems-with-your-device-try-to-reset-your-phone-1205
Hopefully the above proves useful!
