Most annoying is even if you have cards attached to each adult account, unless there is gift card balance, the leader of the family’s card is always used.
So even though my other half has her car attached for purchases and always has done, now my card gets used. Not a big problem but confused the hell out of us at first. More of a problem if you regularly buy content, which we don’t.
Other than that it’s good and also sharing apps is good. So one kid gets minecraft, you can all share it which helps save them cost but also lets them fight as one bought it with their money and the other gets it free but thats life so they have to learn to take it in turns I guess
