Cannot authorize paypal as my payment choice.
I do all I need at pp.com and it sends me to download iTunes. I tried upgrading even though I believed it to be current. Then there is an error about something missing.....
One possibility -- per Payment methods you can use in the iTunes Store, App Store, and iBooks Store - Apple Support PayPal can only be used as the payment method for your Apple ID if the PayPal account is linked to a credit card.
