GooglePlay Console: App doesn't have any in-app products yet.

Okay, I have previously added in-app purchase to apps but this time the warning doesn't go away. In console i get this message "App doesn't have any in-app products yet."

In Google Play Console, I have uploaded an app, i am using Android-in-app-Billing-v3-light. It's an in-app billing library from github. I have added permissions

<uses-permission android:name="com.android.vending.BILLING"/>

This warning doesn't seem to go away. What i am doing wrong? Did google play change it's requirement? Why it's not allowing me get past this screen or warning. Most questions asked had some error with permission but i have added permission. Also published the app in alpha.

With test id it's showing.

Okay, I found what was causing this issue, Google has updated their terms and services and now you need to create merchant account before you enable in-app purchases.

please create your merchant account, check the screenshot
