I used to love family link but the minute I moved from phones to tablets and chromebooks it made them un-usable for my children (both under 13). This is because the restrictions are so inane it blocks everything useful (cannot use Google Play at all, cannot use Youtube app at all - had to install firefox just to fix this, couldn't access websites for school even with "least restrictive" settings for everything). Do not use if you are using chromebooks for your children - okay if only using for mobile phones. Though the lock on Google Play still locks out about 80% of the content I get through Nintendo, Microsoft apps, and other providers.
