Verifying Payment
When I try to set up my family sharing, it tells me that I need to verify my payment. After following all of the instructions, I end up in Account Settings. Here is says "PayPal is not supported on this device. To manage or change your payment method, go to the iTunes Store on your computer". I found one place online where I could edit my credit card information. I have a valid card online, but my phone does not seem to acknowledge this. It still says that I "must verify [my] payment info before [I] can make purchases". How can I successfully change my payment settings in a way that my phone will recognize it?
