Does Unity IAP support promo codes from the Windows store for MR devices? I have a hololens application that I was able to add IAP support when initiating a purchase from the application. Today I tried testing an IAP promo code for a non-consumable good, but Unity is not recognizing that the promo code was applied. Essentially, the ProcessPurchase callback is not being called for promo code purchases. In later testing, I purchased a different IAP product.from within the app, by calling the InitiatePurchase function. When I then restarted the application, ProcessPurchase was being called for the sku that I applied the promo code for, as well as the product purchased through the app itself. Deleting and reinstalling the application also allowed both purchases to be automatically retrieved. At a bit of a loss here for what might be going on. Using Unity 2017.1.3p1 with Unity IAP 1.18.
