Apple Card - Positive Experience so far

Thanks, that finally worked. One thing that isn’t clear in the instructions though, is that you have to setup your bank account in Apple Card first, even if you aren’t going to use it for this payment. I was trying it without a bank account setup yet, and that doesn’t work.

I just made a purchase at Lowes with my AC. Didn’t use my membership card. Just inserted the chip.
Choose email receipt and somehow it knew my email!
WTF?

I applied and got approved for the Apple Card today. It’s in my wallet now. I’m trying to switch my iCloud payment method to use it but keep getting rejected with “please try again later”. Is this supposed to work? Do I need to wait for some kind of overnight cycle before adding it?

Edit: Seems I can’t add any other cards, not just the Apple Card.
