I had an issue using Walmart Pay with Chase Pay today. I went to the register and scanned the QR code like usual, the Walmart app said I was connected but the register did not acknowledge that I was. It wanted me to pay with a physical card.
So I decided to try a self check system as that is what I normally use. Again, it said I was connected on the app but not on the self check kiosk. It wanted me to pay with a physical card.
The managers didn't understand why it was working that way. I paid with the physical card so I probably won't get the bonus, though I didn't receive an alert on the app with my e-receipt so it was indeed communicating with the self check properly.
