@menos @dch @joeress Hmm. I’m not in the UK, so that might be a legal requirement rather than an Apple thing. I have a (US) Apple account with no payment method on it that I use occasionally, but the whole point of Family Sharing for me is sharing paid apps & content, plus my main account has payment info on it anyway.
I don’t see the benefit to Apple of forcing this issue on a tiny minority, which is why I assume this is a government requirement rather than its own.
