How to check if In-App purchase (PhonegapIAP) has been made?

Hello.

I have an app, that was build using C2 R195, Phonegap IAP plugin 2.0.32, Intel XDK. The in-app purchase of an non-consumable product works fine in a beta version on Google Play.

What I struggle with is: I want the app to check whether the product has already been purchased or not. I use the "Has product" condition. If that condition is fulfilled, an action is triggered. The problem is, that the action is not triggered. Does anybody have an idea where I make a mistake? Any bit of help is very much appreciated!

Here are screenshots of Google Play In-App products section and all C2 actions in the app:

Thanks in advance! Sophia
