Yea I have. The only major requirement i can think of is that the address and last name on the PayPal account must match the last name on the card as well as the general address.
Example if the PayPal account has Jamaica listed as the country then the card must be from an address within Jamaica. Also if the last name on the PayPal account is Brown. You can only add cards with the last name Brown. If those conditions are met, check with Scotia and see what them seh.
