Similar Apple Card-related problems. I completed the "pre-order" process on Wednesday (with Apple Card as the payment method), but when I tried to complete the order this morning, the site said my bag was empty. After 20 minutes of refreshing in hopes that the pre-order would show up, I decided to start over. When I did, and selected Apple Card as the payment method, I got repeated "bad gateway" and "something went wrong" error messages whenever I tried to complete the transaction. Finally, after several attempts to go back and re-finalize the transaction, it went through. Then, about 40 minutes after the sales began (and just a few minutes after completing my new transaction), the pre-order finally showed up properly and wanted to be completed. I'm now ignoring it for obvious reasons, and working with Apple Card to get the original authorizing amount dropped from my card (and the actual charge for the taxes removed). Not the smoothest launch ever...
