iCloud storage payment
I bought a gift card for the AppStore/ iTunes to add to my wallet on my iPhone7. I don’t want my Visa stored on my phone. I now have some credit . My question is: can this credit be applied to my iCloud monthly storage bill of $.99 per mo? It still says I need to add a payment method. I thought that’s what I did. Thank you
