Error when purchasing Consumable IAP on Windows Store

Hi,
Some of my Windows Store (UWP) users are encountering this error when they try to purchase a consumable product: PUR-UserAlreadyOwnsContent

I'm using Unity IAP v1.20.0 and Unity 2017.4 (.NET scripting backend, .NET 2.0 Subset).
I'm initializing Unity IAP like this:

Code (CSharp):

1.  
2. foreach (var product in iapItems)
3. {
4.     builder.AddProduct(product.id, ProductType.Consumable, new IDs() {
5.         { product.sku, AppleAppStore.Name},
6.         { product.sku, GooglePlay.Name},
7.         { product.sku, WindowsStore.Name},
8.     });
9. }
10.  

The latest user who reported this issue is running my game on Windows 10 (10.0.17763) 64bit.
Please to note that not all my users are encountering this issue, only some of them!
Any idea why they're encountering this issue and how I can fix it?

 

It works correctly in your testing? I'm not clear on the storeID logic, not sure if relevant. Why are you adding multiple storeIDs to the same product?

 

Hi,
I didn't tried in testing mode, but there is no issue with many users, only some users contacted me to report this issue (I can't determine the percentage of users getting that issue, but surly it's a shortfall).
I'm targeting multiple stores (Google Play, App Store, Windows Store...) and the share they same sku.

 

You generally want to test your app prior to release. If you could provide the device logs from an affected user, it would be helpful. For the users that are reporting the issue, have they indeed purchased a consumable previously? And you've tested this scenario yourself in Production with a real credit card?

 

I'll try to check with the affected users.
What type of logs do you need to identify the issue? The "PurchaseFailureReason" is sufficient or do you need other details?

 

The full device logs, starting with IAP initialization. But first, you'll want to fully test yourself.

 

I just tested with real credit card and I'm able to purchase twice the same item.
I'm still awaiting for a response from user who encountered the error (I don't know if even I'll receive a response), but I've attached a screenshot of the issue that I've received from that user.

 

You'll need to find the specific steps these users are taking during their purchase flow.

 

I hope I'll get a feedback from them, sent emails but no response from them till now.
Meanwhile, please to tell your team to be aware about the issue, maybe they can find a way to reproduce it.

Hi,
Here is the details that I've obtained from one user:
OS: Windows 10 (10.0.17763) 64bit
Device Model: Inspiron 5749 (Dell Inc.) DESKTOP-XXXX82
Device Architecture: Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz
Device Resolution: 1600x900
Device Memory: 8103
Device Language: FR
Country: Canada
Unity version: 2017.4.25f1
Platform: UWP (.NET Scripting Backend - .NET 2.0 Subset)

The Unity IAP log:
Unity IAP version: 1.20.0
ItemID: coin20
DateTime: 2019-04-21 00:25:24
UnityIAPInitializeSucceed: True
TransactionID: 5b099166-1ae8-4f5d-bc86-82a23f1456d9
LocalizedPrice: 2,49 $
AvailableToPurchase: True
PurchaseFailureReason: Unknown
LastStoreSpecificPurchaseErrorCode: Unknown

Is that helpful to identify the issue? Or there is any other log that I can obtain and it might helps to identify the issue?

 

Yes, the device logs would be necessary.

 

How can I get that logs? Any doc how to get these needed logs?
I want to add that I'm also seeing this initialization error for few users: AppNotKnown

 

Is it working as expected during your testing?

 

Yes, I've also tested by purchasing with a real credit card and all is OK for me!

 

Hi @/jeffdunity3d,
Are you able to reproduce this issue on your side? I'm still seeing many users encountering that issue :/

 

Are you able to determine if the affected users are non-US? I did notice FR as Device Language
