Samsung Unity IAP: Product does not exist in this store.

I have an app which has been live on Apple/Google for 8 years. I published it on Galaxy Store. I am getting the following error in production which doesn't show up in development and testing: “E9202/6050: Product does not exist in this store”. The error occurs when I try to purchase a non-consumable in the app from the Samsung tablet. The app has a total of 3 IAPs.

- Unity IAP initializes correctly
- It is set to target Samsung from the editor
- In app purchases are obtained correctly during IAP initialization and IDs match

Attached is the logcat from the production app downloaded from Galaxy Store (not sidel oaded). The app is called "Human Design App" and is available on Galaxy Store in the US.

IAP gets the in app purchase correctly

For publishing to Samsung, you'll want to use UDP https://unity.com/products/unity-distribution-portal

 

Jeff, does this mean that Unity IAP doesn't support samsung in app purchases directly? I didn't see this anywhere in the documentation.

 

Correct, we are updating the documentation and continuing to discuss. But currently, Unity IAP is using an earlier version of the Samsung purchase API, UDP has been updated.

 

Got it thank you!
