This morning I noticed that Apple is returning a 503 HTTP code when I try to start a checkout using Apple Pay JS and hit their servers before calling completeMerchantValidation.
This was working code, and I also noticed GrubHub seems to be erroring when I try using Apple Pay on their site, and other sites that support Apple Pay aren't showing the button at all right now. Pretty sure this is something on Apple's end, but I wanted to check if others are observing this behavior as well.
