I went to buy an app and was told I had to enter last 4 digits of my wife's CC number (as she "controlled" the Family Sharing account, or whatever)... didn't want to bug her with this, so I turned off Family Sharing so I could pay for my own dang apps. But that also disabled Location Sharing and shared Calendar with her (so I had to turn it back on and bug her to accept a new invitation anyway). What gives? Is there any way to do Family Sharing and not share app payments(?) Thx
