Apple Pay stopped working.

Series 10 watch running os11. Set up Apple pay - worked perfectly, now not. iPhone Apple Pay - same card working still. Get this message on my screen when I try to use it, but it’s not at all clear what to do.

“Confirm with AssistiveTouch Is Enabled

To confirm payment, open the action menu and use AssistiveTouch gesture to confirm. You can turn this off at any time in

Accessibility settings.”

I’ve tied it with AT on, off. Still not working.

can someone walk me through so I can just use the side button as it was working. 🤯
