Family Link challenges

Does anyone have google family link working for their supervised child's account to their liking? I am having challenges and its really frustrating.

* Family library app purchase are not available even if they meet the requirements * I cannot install streaming services, netflix, disney plus, hulu, etc * even though I have adjusted settings to allow an installation of a game (Among us) the game still states that it is not permitted.

it really is maddening and I feel bad that I am trying to do a good job in limiting my child's access to content to them safe.

the only thing that actually works is screen time and app time limits. any advice welcome.
