So, in consulting with my bank, Goldman Sachs, and an Apple Advisor, it was determined that:
My wife attempted to pay down credit on our jointly owned Apple Credit Card using her Apple Cash balance.
She accidentally entered the amount as two cents over what was available on her Apple Cash card.
All but two cents successfully transferred to the credit card from her Apple Cash account, but the remaining two cents were withdrawn from the linked bank account on her Apple Cash card (an expired debit card of ours).
The two cent transaction was reversed and the connected bank accounts in both of our Apple Credit and Cash Cards were automatically cleared by Apple in order for us to reconnect and update our bank information.
Didn’t know a debit card could be linked to Apple Cash. 🤷♂️
