In-app purchases not working

Hello, I have a problem with mobile in-app purchases, the game is on Google Play, but it’s simply not working. My question is - is there a GDevelop related issue that could be noticed from the images I provided? The problem could be on Google Developer settings, but I’m currently focused only on GDevelop.
Thanks in advance.

Use the condition “Store is Ready”. Also, your game should be published at least on testing mode on Play Console.

How to go live with IAP please? in my app it’s work but just test mode, why?
