Nothing happens when I put my finger on Touch ID.
I have Apple Pay set up and can use it online. I don’t understand how to use it in stores. I’ve tried pressing Touch ID (the home button), holding my finger on it, starting with phone locked or unlocked, from home screen or a different screen. My Touch ID works fine for everything else. And sometimes the Apple Pay pops up when I’m trying to do something else with the home button, but never when I intentionally try to get it. What am I doing wrong?!?!
iPhone 5s, iOS 12
