Troubleshoot tap to pay on iPhone

[Caldwellb02]

I used to be able to use tap to pay on my iPhone but now it doesn’t work. I can take manual transactions but not the type to pay. My phone is up-to-date. I uninstalled and reinstalled the Square app. I had rebooted the phone anybody got any other ideas?
