Upi pin failure - pls help happening with all my upi credit cards

[bikramnitj]

Hello,

So i recently updates my iphone to ios18- not sure if thats the problem.

So it wanted me to reset my tata neu infinity upi pin on upi transactions through credit card. The process sends and otp which i enter and when i proceed with enter upi pin and confirm upi pin to set it, the end result is failure message

Same case, with recent kiwi rupay card(yes). I am unable to set for that too. It takes me all to the process but in the end fails it ..
