Windows Universal App - In-app product for Windows 8.1 not working -

my app published on windows store , windows phone store. consumable in-app products working windows phone not windows.

this code not work example:

var listing = await currentapp.loadlistinginformationasync(); 

it gives exception:

hresult: 0x801900cc 

and when want purchase in-app product, tells me app not found in windows store. published today , can download store.

i doing in msdn documentation , exact same code windows phone version , there works. had deactivate in-app purchasing in windows 8.1 app because otherwise wouldn't pass certification because of problem. in-app products defined in store during submission. , app has correct name , publisher infos in visual studio 2013.

so know problem here?

ok seems have make sure in app products don't crash when no internet connection or server down or app not published yet. because otherwise certification not activate products when defined before submitting. when handle exceptions , app doesn't crash activate in app products.
