Why does my Apple Card say "Payment Failed" when used in Apple Store?

Whenever I try to use my Apple Card via my phone with the Apple Store it says “Payment failed”. (NOT DECLINED).

I use the Apple Card for everything else (ie Nordstrom just the other day) and it goes through no problem. But when I wan tot buy something apple.com PAYMENT FAILED

Just got off phone with cc and they say it’s not an issue with them. Apple can’t figure it out. Really apple???
