I am using the basic PP integration with BigCommerce. Not Braintree.
Since moving from OSCommerce to BigCommerce my chinese customers can no longer use UnionPay cards. They have been deprecated in Braintree but no one can tell me about the standard set up.
I don't know if I should use the additional function that's offered of "pay with credit cards" in the BC admin set up. It didn't seem to help when I tested it.
