holydarkness said from his side it was working and you are saying even with two other phones it's not working. Is there something about the configuration of the phones you have?
the part that @holydarkness was referring to as working is that there are now other options for KYC besides VISA, not that the KYC process is working.
the only thing that comes to my mind with the VISA thing is that you've maybe used a VISA card to play and they are asking its details, but it's a crypto casino so I'm not sure about that.
if they were asking him for a VISA card, they could have made it more clear. i thought they were asking him for a travel VISA, not a bank card?
