Following the tutorial for Google + Unity Purchase validation (Tutorial), it is mentioning that we should set the Id as the same of the purchase PlatformId, which comes from the Play Market. However, we cannot change the item id (no option), which made us think that it probably meant that we had to set the Friendly Id instead. Apparently that is not the case, since we are getting the following result to our validation request:
-/Client/ValidateGooglePlayPurchase: There is no item in the catalog with an ID matching the product ID in the receipt
How is this suppose to be set exactly?
Which Id is the server using to check the purchase and how can we change it to match the one used in the store?
