Trying to get in app purchases working

Development Platform & Builds

I’ve followed the steps on the above page, set up in app products on Google Play and used InAppPurchase node in my menu blueprint with my in app purchase ID in the product identifier of the purchase request in BP, and triggering in app purchase does nothing. The game has been uploaded to Google Play and is set in closed alpha testing and I am triggering it from there, both on my device and a test device (not linked to my account).

This is not exactly my strong suit, so i’m not really sure where to turn. I must be missing something. This is the last thing I really need to do to finish it.

Any help or pointing in the right direction would be greatly appreciated. I can provide more information if needed.

Thanks,
Joe

I have an older game that received that warning but Google Play Services work on it, still, while I have another that I’m trying to get running that also has that warning but doesn’t work with said Services. It seems like that’s not part of the problem.
