What should I do if payment link does not work?
Reasons that the payment link does not work might be:
1) The payment link is only valid within 72 hours after sent by supplier. If it expired, supplier need to send it again to you to pay.
2) If it shows 'ERR_ORDER_MISMATCH, The order does not match the user', it's because you logged in a wrong account where the order does not exist. Please log in the right one to find this order and pay.
3) If it shows ' ERROR 404! ', it's because the order does not match the user. Please log in the right account where the order exists, or because the payment link expires and supplier need to send it again to you to pay.
