Is there anything more annoying than when your credit card expires? We feel your pain. Or maybe that's not at all why you want to update your credit card info...... #awkward.
Anyways, DiveThru does not store any credit card details. To update your credit card and payment details, you need to go to your AppStore, Gplay, or Paypal account.
Then, you'll be good to go! Nice and simple.
