unable to add credit/debit card or set up auto pay

Same problem.  I have a Costco Visa that was used for auto-pay.  I lost it, so they issued me a new card.  Tried to delete the old card, then add the new one.  I think that was the mistake.  Maybe add the new one first.  Anyhow, it will let me add my card to the wallet, but won't let me set it up for auto pay.  Won't let me actually make a payment.  It also won't let me add a Mastercard debit card at all, just gives an error. Customer service can't get any of this to work either.  They are sending it to engineering and supposed to call me back tomorrow.  I hope they figure it out, but I'm really worried based on what you all have written.
