User's purchase success, but OnPurchaseFailed() is called

On the chance that you are able to reproduce, can you provide the device logs? https://forum.unity.com/threads/how-to-capturing-device-logs-on-android.528680/

 

Yes, in our tests we weren't able to reproduce it, it seems to be happening to players and it's not consistent for the players as well (thank god!)

 

We had encountered yet another purchase failure, with the player stating he was using his home WiFi connected via fiber,
selected the "1-tap buy", provided fingerprint for verification, then it confirmed. However, when the player got back to the game it said failed."

It doesn't sound like it's a network issue...
Could that be something with a different unity component in the process? Maybe a report to a Unity Analytics backend which returns an error?
Or a transaction verification failure which isn't supposed to fail?

 

Have you tested using fingerprint verification? The stores may return User Cancelled in the purchase flow if anything interrupts or puts up a separate dialog (even during the native purchase flow)

 

Hello

faced the same problem: users gives us purchase receipts, BUT in our analytics and in logs we see that unity purchasing returns :

iOS

[ message: APPLE_Cannot connect to iTunes Store : SKErrorPaymentCancelled ],[ reason: UserCancelled ],[ productId: boardkings_special_package_2 ]

Android

[ message: GOOGLEPLAY_1:User Canceled (response: 1:User Canceled) : BILLING_RESPONSE_RESULT_USER_CANCELED ],[ reason: UserCancelled ],[ productId: boardkings_bundle_20 ]

where
message => failureDescription.message
reason => failureDescription.reason
productId => failureDescription.productId

and failureDescription received from ITransactionHistoryExtensions.

Do you have any progress in investigation of this issue?

 

No updates yet, we haven't been able to reproduce. Can you confirm if these users are using fingerprint, faceID or other secure login? Our theory is that perhaps such a login dialog that pops up can cause the store API's to return UserCancelled, and we pass along the status.

 

Hello,

On iOS I recently hit similar(?) bug: if user account has no payments method selected the OS asks him to provide one. After completing all necessary steps a message box appear that purchase is successfull but returning to game I've got error message that purchase is failed and right away another message that purchase is successfull. Unfortunately this was an unlogged session so no logs are available. Tested on real device with real account.

 

Thanks for the tip! This is good information.

That looks like code in your ProcessPurchase, not onPurchaseFailed. Can you share your code? Product is named "1000", could you compare to an alpha-only product name, as a test? And it shows your app resuming (onGameResume), not sure if relevant. And please test with IAP 1.23.1

 

I checked with IAP 1.23.1 and with alpha-only product name - the same story.
(In GP - purchase was done, and money was withdrawn from card).
The same issue with Purchase of NonConsomuble item - after success purchase - Failed msg came, but CheckBuyState method for this item return "true"

 

You have additional delegate callbacks that I would not be familiar with. Please test with the Sample IAP project to compare, the issue looks limited to your code. Also, I suspect it may be due that you are calling Initialize during Awake, you should not do that. You want to initialize IAP only once in your game, as a singleton.

 

Given the case that this might happen, are there any workaround or suggested ways to fix this?
Recently ran into this issue where some user makes a purchase, and did not receive their stuff. They are billed.

 

We are in discussions with Google regarding their Google Billing library on this issue. We are working on the next version of Unity IAP which should include an updated library

 

Hi @JeffDUnity3D, is there any information on when this update will be available (weeks, months, a year etc.)? I have previously made a similar post (https://forum.unity.com/threads/unable-to-test-google-play-slow-card-payments.782006/) and we struggle with slow payments and having no way to test the user flow without the updated Google Billing library.

Due to the high volume of complaints in India, which has become a core market for us and makes heavy use of the slow payments, we may have to look at writing our own wrapper around the library for Android if the integration is still some time away (The comment in the thread i made was from January suggesting the same thing that the Billing library would be coming in an updated library...)

 

Still getting the same issue on Unity 2019.4.21f1. On our case, a player does a purchase (for product A) successfully, and a few seconds later does the purchase again where it fails but the player has been charged. So basically unity called OnPurchaseFailed after repurchasing (product A).

 

What version of IAP are you using? Please provide specific steps to reproduce with IAP 3.0.1
