Taobao Alipay cannot be bound.
Dear, your new Alipay account has been bound to Taobao, but it is not your old Taobao. I suggest you log in to Taobao website with Alipay account and check the name of Taobao member displayed in the upper left corner. If you can't pay by express payment, I suggest you add a bank card to enable express payment first. If you have any other questions, please contact Alipay's exclusive service hotline 95 188 for detailed consultation.
