[UWP] Unity IAP Initialize failed without any callback

Hi

There was a problem while updating the version of our game from the Windows Store.
I tried UnityPurchasing initialization, but neither OnInitialized nor OnInitializeFailed functions are executed.
In the previous version, the in-app purchasing worked well.
I want to know why the initialization problem occurs only in my Windows build environment.

Unity Version : 2018.4.17f1
Unity IAP version : 2.3.0
Build Environment : AMD Ryzen 7 4700U, Window 10, x64

Thank you

 

I'm seeing something very similar on 3.1 and 4.0.3 with Unity 2019.4: https://forum.unity.com/threads/unity-iap-uwp-throws-exception-during-init.1170815/

I had a subscription that was not set to Electronic Software Download in the windows store interface, but after correcting that I'm still stuck with initialization failing with "NoProductsFound". The error still triggers in exactly the same area as yours. This is the similar stack from your log:

I'm suffering from this issue too. Have you been able to find a solution to this? All help is very much appreciated!

 

The best solution is to not use Unity IAP in UWP. They keep breaking it and they ignore requests to fix it.

 

Agreed, Microsoft changed the API. Also, the market share for UWP is now less that 2%. We are looking to support other stores on the Windows platform like Steam. Closing this thread.
