    This is happening to me on Android using Unity IAP version 2.0.6

    Flow goes like this
    • Initiate Purchase
    • Click "1 Tap Buy"
      Minimize app while "processing" but don't kill it
    • wait a second or two and re-open/re-focus app
    • Unity IAP calls OnPurchaseFailed with reason Unknown
    • Unity IAP calls ProcessPurchase

    I'm guessing this is not by design and is some kind of bug?

    Correct, this should not happen. We will look into it, thanks for the heads up.

    Realized I never actually wrote down the version we are on. Just updated my original post with the Unity Purchasing Package version

    It's a bit confusing, but that is the Package Manager version. We generally go by the Asset version. In the Unity editor, go to menu Window/Unity IAP/IAP Updates... and it will show the version.

    Also this might be related but if I do the same flow but kill the app instead of minimizing it ProcessPurchase gets called twice after the IAP System initializes

    Hello chrismarch,

    Without knowing the full details, it's hard to tell, but I believe this might have been caused by a deferred purchase which was getting processed when purchases were being fetched.

    This is something that had to be handled in ProcessPurchase prior to IAP 4.6.0, but since that version, this is handled by IAP directly.
