Family Sharing Credit Card Problem
I have searched and see that others have had the same problem I'm having but the solutions posted aren't helping. I am setting up family sharing on my iPhone. I am being asked to enter the security code for a credit card that is no longer active. I have checked every possible place to see where this credit card number maybe stored and I can't find it. I have: 1- Logged onto iTunes on a computer to see if the old credit card number is there, it is now. 2- Deleted my new credit card and added it again. 2- Turned off Family Sharing and turned it back on again. 3- Restarted my phone. Nothing seems to work. I'm still being asked for the old credit card information. HELP!
iPhone 7, iOS 11.2.6
