When I open the Passbook App I see nothing but an introduction to Passbook, then scan code at the bottom of the page or find apps for Passbook. I dont see where I can add my credit cards?
I Have the same issue on my iPhone 6 plus, on my iPad air 2 there is No passbook app at All. I need to change some card details and it seems there is no way to do this As there is no menu option for passbook on either device.
