Apple charges from my ex wife's Apple ID
My ex wife is making Apple purchases (Apple TV and storage) using her personal Apple ID but the charges are going to my credit card and neither of us can work out why it's happening as she appears to be using her own card on her account.
We have a Family set up for our two kids (of which I am the 'organiser') so we're wondering if it's something to do with that? But we can't find out where and how to change it.
