India Citi Bank Shop pay error adding card

[turanammo]

I am trying to use Shop Pay. Adding my Citi Bank India Credit Card (Visa Platinum) gives error "There was an error adding this card". Please see the picture below. I have entered the same address as registered with my bank. Verified multiple times with other credit cards and debit cards (Axis, Federal etc) but all threw the same error. Do you support India-issued debit and credit cards?
