Getting "Please complete this mandatory field." error on the Apple Store app for iPhone
When I try to add my Payment Method to make a purchase, it gives me this error message. I've tried re-typing everything twice and nothing seems to work. I've tried keying in my Credit Card details manually as well as using the camera. The only fields I've left blank are "Optional" (Company Name; Apt., Suite, Bldg.; Alternate Phone).
