How to stop Family Sharing in-app purchases
I am the organizer of a family. Today I said OK that another member could buy gems in Clash of Clans via in-app purchase.
That person had to enter the password for his Apple ID. Then money was drawn from my credit card.
Now, I approved this purchase. But now I'm a bit worried that my credit card could be maxed out if other members of the family makes crazy in-app purchases and only has to enter their own passwords!?
Is there a way for me to confirm each and every purchase?
