Why didn't Todd receive the goods, indicating that they had been delivered?

This is because the seller clicks on the delivery, and the time exceeds the time specified by the system to automatically confirm the receipt.

In this case, contact customer service in time.

Confirming receipt means: if you have received the goods and there is no problem, you can operate "Confirming receipt", and Alipay will pay the transaction money you paid to the seller after receiving your confirmation information. Entering Alipay password will not result in the second payment.
