Apple Pay not accepting any Visa Cards
So recently, all of a sudden my iPhone's ApplePay suddenly stopped accepting Visa Cards. I am able to add all network payment cards with the exception of Visa Cards. When I try, it says "contact card issuer". I have tried multiple visa cards from multiple countries and no luck.
The banks have proved that there is nothing wrong on their end as all those card work perfectly for other Apple Devices I have. Even Apple hasn't been able to figure out why is this the case.
I have this issue since iOS 15.4
How do I fix this?
