To all those who are facing the amazon UPI issue ,check for any system update. I don’t know what happened but my amazon pay UPI is working now. Earlier I also used to have the same issue. I have tried many times ,even after some security updates also it didn’t work . I haven’t contacted or reported this issue to any one but the issue is resolved now for me .Even after the recent update it didn’t work for month but it is working now . May it is the problem with amazon. I even thought of flashing my phone but luckily it is working now without flashing.
My software is 3.2 with Pacman-V3.2-250620-1021-IND build number .
My phone is nothing phone 2a.
