Bug InvalidOperationException when receiving purchases

UnityIAP version: 4.7.0
Error: InvalidOperationException: An attempt was made to transition a task to a final state when it had already completed.

This error sometimes occurs for some players. After adding logs to the QueryPurchasesWithSkuType method in the GoogleQueryPurchasesService, it was discovered that there was a multiple call from the billing client.

Any updates for this? Recently I discovered my game is still having the same problem

 

Oh, God, no... JNI issues in purchasing plugin? Again? Really? Really-really?
Hey, Unitytech, what are you doing? How long will broken versions be released?

Faced the same issue in Unity 2021.3.32 + Unity Purchasing v4.10

 

Still happening with Unity Purchasing 4.10.0. Typically we're seeing this from users with an unstable internet connection or perhaps a corrupted Google Play Services installation.

For example, in the logs we're seeing the Unity IAP billing system fails to find products (Reason: NoProductsAvailable) or Google Play Game Services fails to initialize.

Seems to happen on a variety of devices and Android OS versions.

 

I have the same issue with Unity Purchasing 4.10.0. and Unity 2022.3.18f1.

 

Idiot unity developers !! same issue 4.10 version and they do not even think to solve this issue !
