    HI,I need help
    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.
    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.

    Hello,
    Based on Google Play Help, the QR code remains in the purchase history once it's generated. This means a pending purchase was created which is why there's no OnPurchaseFailed callback, since it can be paid for at a later time.

    Hi,
    Can I only use OnApplicationFocus to know that he has returned to the APP? Or is there another callback that can be used?
    Thanks for answering.

    Yes, that should work.

    There's also OnApplicationPause that could do what you're looking for.
