@modernator24 Your code looks ok, although you are wiring up your own listeners which is not necessary and may be leading to your issue. You are properly returning Complete from ProcessPurchase, can you place a Debug.Log statement just prior to that line to confirm that the code is indeed executing as expected? Debug.Log statements will show in the adb logcat logs. You could compare to the Sample IAP Project v3 here, I haven’t received any such notice. Your code is fairly similar except for your listeners, Unity IAP already provides the listeners Sample IAP Project
