I have a customer who reached out saying Apple Pay isn’t working. I checked on desktop, and it isn’t working for me either.
I thought it was only for mobile devices??
Is your desktop a Mac? I believe apple pay only shows on IOS devices.

There's currently no indication of a problem, but there have been a few reports of it being down today. You and your buyer can report it if you think there's a problem. The more reports they get, the more likely it's actually down and having an issue and they'll look into fixing it.
