HI, I believe that setting is Online Dashboard, Settings, Checkout, upper right Advanced Settings, scroll down to APay, GPay.
Hope this helps!

Nope. I've always had it checked "on"
Having the same issue... Google pay is showing up just fine for my online store in the cart. But no Apple Pay. It does show up if I use any of my direct checkout links but only on those direct links. I have tried on several different Macs, iPhones, and iPad (yes, using Safari on Big Sur, iOS 14.4). I use Apple Pay for other things all the time so it's not my devices.
