We started using Visa Checkout in July. It worked perfectly until a few weeks ago when it stopped accepting Master Card and Discover cards for no reason. I have double-checked that we do allow the following credit cards on our merchant account: Visa, Amex, Master Card, Amex.
Has anyone encountered this? Can anyone point me to a solution? I am at a loss.
