PayPal wants me to “add a bank account”, another funding source. Credit card isn't working. Why?
I've used PayPal for my business for a long time. Sometimes PayPal doesn't trust credit cards. Debit or direct bank transfer are reliable. There is also a charge for using a credit card but I don't think that is the reason. You may be trying to purchase a high value item. That would be a possible reason why PayPal allowed you to use credit cards in the past, but will not allow you to do so now, for these particular transactions.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
