Hi! We are getting message about an issue with Incorrect usage of IAP
"Your app or game has not implemented an Observer corresponding to an IAP Purchase that you have initiated. This could lead to failed purchases."
We have a live version for several months & we've done no changes in our IAP usage implementation. PurchaseListener, PurchasingService & Response Receiver are on their places. So, can you, please help with investigating the problem & is the problem critical for update submission, which is planned in several days?
