I did not receive an OnPurchaseFailed callback in Unity IAP 4.7.0

I am using Unity 2020.3.35f1 with IAP version 4.7.0 in a game in Thailand. When using Google payments with promptpay as the payment method, I obtained a payment code. However, when I cancelled the purchase, I did not receive an OnPurchaseFailed callback.

Unity IAP will consider the call to UnityPurchasing.initialize completed before invoking the correct callback IStoreListener- 1

It should be said that I will receive OnPurchaseFailed when I leave the google Play payment page before I get the payment code, and the whole process is normal. And my normal purchase can also be successful, only after I choose to get the payment code and leave the google play payment page will I not receive it

I got the same problem, any update?
