As title says
VTD cannot be manually granted, and there is no documentation about manual add/reduce. For example, VTD can be added when ConfirmPurchase API is called or a receipt is validated sucessfully via ValidateGooglePlayPurchase during a real-money purchase process, which also means there should be actual transactions happening.
That's not enough. My game is pay to play. I'd like to set starting VTD to the current price of the game. Currently I'm also using Steam validation for iaps which works fine and VTD does increase but codes to redeem iaps are also sold by other provider. I'd like to increase VTD everytime player uses that code.
I also have the same problem, this shouldn't be the accepted answer...
