On iOS and Android I do not have this problem. The only change I made is that for WinRT I used product IDS from the Add-ons section of the Window Store. The QtStoreSimulation.xml is deactivated.

My expectation was that this was all I had to do to use in-app products on WinRT platforms.

When I try to purchase something I get:

qml: Purchasing SKU: com.gsoftteam.connectwaterpipes.gold_1
Attempted to purchase unregistered product

I also see this in my debug output:

 info:get_LicenseInformation() invoked.	[Windows::ApplicationModel::Store::CurrentAppFactory::get_LicenseInformation]

My app is live here: https://www.microsoft.com/en-us/store/p/connect-water-pipes/9nhh0zcdzbm2
Is there something I am doing wrong? Does anyone else have this problem.
