I create a new IAP in store with the Product ID "Donate". Then I make request to this IAP in the app, here is the code:
var purchaseResults = await CurrentApp.RequestProductPurchaseAsync("Donate");
However, when I call the function in my windows app, an error message dialog is shown:
Choose another item : This in-app purchase item is no longer available in My App Name
and I tried call
var listingInfo = await CurrentApp.LoadListingInformationAsync();var productListings = listingInfo.ProductListings;It seems that there is no product in the list.
How would this happened? Thanks!
