The answer does not come to API_callback at FAPI.UI.showPayment when there are not enough OKs and I buy them in addition. What to do?

Question

Classmates

I am making a purchase. For example, a product costs 10 rudders. I have 5 OKs. When you try to purchase an item inside the game, a window for buying OKs opens. I buy them. In the Odnoklassniki window it says that the purchase was successful. The purchase goes through and everything is fine in the payment script. It sends back true. The problem is that the response to API_callback does not come. What can be done about this problem?

Answer 1

The same problem.
