title: Azure AD B2C not redirecting as expected after signin / signout
body: <p>I have created a asp.net mvc core web app and am trying to use Azure AD B2C.
  In the portal, the redirect urls are as follows:</p>
  
  <p>Redirect URI: <a href="https://localhost:44319/signin-oidc" rel="nofollow noreferrer">https://localhost:44319/signin-oidc</a></p>
  
  <p>Logout URL: <a href="https://localhost:44319/signout-oidc" rel="nofollow noreferrer">https://localhost:44319/signout-oidc</a></p>
  
  <p>My App settings:</p>
  
  <pre><code>  "AzureAdB2C": {
      "Instance": "https://myApp.b2clogin.com/tfp/",
      "ClientId": "myClientId",
      "CallbackPath": "/signin-oidc",
      "SignedOutCallbackPath ": "/signout-oidc",
      "Domain": "myApp.onmicrosoft.com",
      "SignUpSignInPolicyId": "B2C_1_SignUpSignIn",
      "ResetPasswordPolicyId": "B2C_1_PasswordReset",
      "EditProfilePolicyId": ""
    }
  </code></pre>
  
  <p>My ConfigureServices():</p>
  
  <pre><code>services.AddAuthentication(AzureADB2CDefaults.AuthenticationScheme)
      .AddAzureADB2C(options =&gt; Configuration.Bind("AzureAdB2C", options));
  </code></pre>
  
  <p>My Configure():</p>
  
  <pre><code>app.UseAuthentication();
  app.UseAuthorization();
  </code></pre>
  
  <p>When I sign in on a page (not homepage), I am successfully logged in but redirected to home page. When I sign out, I am redirected to the Azure login page, but successfully signed out. None of the pages require authorization currently.</p>
  
  <p>Am I missing something?</p>
