Unfortunately, Im glad that I am not the only one. Heres the real deal, I spent a lot of time on this. Apple chose to not allow this card to be utilized by 3rd parties, which apparently PayPal is considered. I spoke to a customer service agent at Apple and Goldman, multiple times, and got a variety of answers. I was first told its because of the third parties and then since PayPal is Apple Cards main competitor. But be aware, the card wont work on your eBay account either. Since eBay and PayPal were once combined, and have now since separated, the transactions still process through PayPal (they still process eBays transactions). So please add eBay to the places Goldman Sachs Apple Card wont work.
Oh btw, when you use your card through PayPal or on eBay, the transactions come through as fraudulent rather than what should be an error.
