Setting WinAppId not working?

[ghost]

I have a scenario where I have already created Facebook APP with existing Windows Store SID which is different from the one I have. I can check it with:

WebAuthenticationBroker::GetCurrentApplicationCallbackUri()->DisplayUri;

So I am tring to set WinAppId from the App in developer.facebook.com

sess->WinAppId = xxx // Where xxx is the ID from developer.facebook.com

Yet no matter what WinAppId is set it always run while Windows Store SID (in developer.facebook.com) is equal to an ID I get from WebAuthenticationBroker::GetCurrentApplicationCallbackUri()->DisplayUri

So my question is:
If it is possible to set sess->WinAppId to be different than the one I get WebAuthenticationBroker::GetCurrentApplicationCallbackUri()->DisplayUri; ?
Or I could just change Windows Store SID in visual studio somehow?
