title: Getting error "Invalid Dynamic Link - Blocked" error when user selects Login link
body: <p>I'm trying to implement email sign-in without password, as per the instructions on <a href="https://firebase.google.com/docs/auth/android/email-link-auth" rel="nofollow noreferrer">this page</a> and when the recipient selects the link in the login message, they see the following message:</p>
  
  <p><a href="https://i.stack.imgur.com/mat6Y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mat6Y.png" alt="enter image description here"></a>
  I don't get this. The domain pento-2a27b.firebaseapp.com IS whitelisted, since it's already included in the list of authorized domains:</p>

  <p>as is the dynamic link:</p>

  <p>so what's Firebase complaining about?I tried sending the link both with and without the path component 'signintoapp' and got the same result.</p>
  
  <p>BTW, the relevant parts of my code look like the following:</p>
  
  <pre><code>        final ActionCodeSettings actionCodeSettings =
              ActionCodeSettings.newBuilder()
                      // URL you want to redirect back to. The domain (www.example.com) for this
                      // URL must be whitelisted in the Firebase Console.
                      .setUrl("https://pento-2a27b.firebaseapp.com")
                      // This must be true
                      .setHandleCodeInApp(true)
                      .setAndroidPackageName(
                              "com.chiaramail.pento",
                              true, /* installIfNotAvailable */
                              "140"    /* minimumVersion */)
                      .build();
  </code></pre>
  
  <p>and</p>
  
  <pre><code>        alertContinue.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              mAuth.sendSignInLinkToEmail(emailAddress.getText().toString(), actionCodeSettings)
                      .addOnCompleteListener(new OnCompleteListener&lt;Void&gt;() {
                          @Override
                          public void onComplete(@NonNull Task&lt;Void&gt; task) {
                              if (task.isSuccessful()) {
                                  Log.d(TAG, "Email sent.");
                                  signinAlert.dismiss();
                                  settings = getSharedPreferences("Five-to-Go settings", Context.MODE_PRIVATE);
                                  SharedPreferences.Editor editor = settings.edit();
                                  editor.putString("EMAIL", emailAddress.getText().toString());
                                  editor.commit();
  
                                  Toast.makeText(LoginActivity.this, getString(R.string.email_confirmation_sent),
                                          Toast.LENGTH_LONG).show();
                              }
                          }
                      });
          }
      });
