Hello, I know this is currently not available, however it is something meta is severely neglecting. Meta needs to allow 2 parents to manage a child's meta account and app approvals. My children's accounts are currently managed by myself, as I bought the devices. However due to my work routine I am not always able to approve purchases during the time the children are with their mother, while this is definitely a first world issue, it's also something many other tech companies have implemented without issue- Google family link for example allows 2 separate adults to manage multiple children's accounts. This is a much needed feature that I have seen many people ask for
