Hi Derren!
First of all, thanks for your reply,
I took some screenshot for easyier for undestand. My problem is when i turn on NFC, like the picture:

the typical NFC icon in the upper right corner does not appear, and when i try to pay with NFC, the card machine. does not detect my nothing phone 3a pro
I managed to pay once, after being like 20 seconds walking around with the phone to find the NFC antenna, but I have only managed to pay 1 time, and when I try to pay maybe I’m a minute trying to pay.
