I’m attempting so as to add a In App Purchase in unity for android however once I push the button that launch the code I get this error: PurchaseProductID FAIL. Not initialized.

There is not any extra error on logcat console. I’ve a closed take a look at printed on play console and set on IAP unity service.

the method get the InitializePurchasing methodology however not the OnInitialized or OnInitializedFailed strategies.

right here is my code:
