App auth never ends

[mediaexplorer74]

Hello, Nick!

I just compiled your "OneNote API work" example.
Sorry but after entering Login/Password the authorization never ends :(

I using Azure Active Directory admin center for my app registration. Under Redirect URI , I choosed the value : https://login.microsoftonline.com/common/oauth2/nativeclient

The problem is here :
<graphControls:AadLogin x:Name="AadLoginControl"
HorizontalAlignment="Left"
AllowSignInAsDifferentUser="False"
SignInCompleted="Login_SignInCompleted"
SignOutCompleted="Login_SignOutCompleted"
Visibility="Collapsed"
/>

Event "Login_SignInCompleted" never happened. Idk how to fix it :( Please help if you can...
