I had an Apple Card for two months. It was the worst card I've ever used. It was rejected for ~5% of all transactions, randomly, online and in person, always with error codes no one could diagnose or correct. All I could do was call Goldman Sachs, who would tell me to try swiping it again, huh, that should have worked, we don't see any record of a transaction ever being attempted, and after half an hour with them they would tell me to call Apple and after an hour on the phone with Apple they would tell me it was Goldman Sachs' fault. I had more rejected transactions with my Apple Card than with every other debit/credit card I've ever had in the previous twenty years combined. Total crap, and completely incompetent, irresponsible "support". I cancelled it and went back to my bank cards.
