Help with child account

Hello, so i just found this sub reddit and thought it'd be a waste not asking here, A freind of mines accounts is a child account and meta wont let us play some games, and the games we can play (like gorilla tag) are sevierly limited to what he can do (cant join private servers at all on Gorilla tag)

On the Perants app the option to disable all protection is grayed out and we cant turn it off, he is young (10-15) but knows his stuff with online activities and his mum trusts him, but it wont let us turn off the limits on any game.

His account was fine for a while then something happened and now all the limits are stuck on... its like it got changed to a child account for no reason!

Any ideas?

PS... freind asked me for help as Im usually the tech support, but Ive tried many things and cant get it to behave how we want.
