Getting error "Invalid Dynamic Link - Blocked" error when user selects Login link

Question

I'm trying to implement email sign-in without password, as per the instructions on this page and when the recipient selects the link in the login message, they see the following message:

I don't get this. The domain pento-2a27b.firebaseapp.com IS whitelisted, since it's already included in the list of authorized domains:

as is the dynamic link:

so what's Firebase complaining about?I tried sending the link both with and without the path component 'signintoapp' and got the same result.

BTW, the relevant parts of my code look like the following:

        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();

and

        alertContinue.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mAuth.sendSignInLinkToEmail(emailAddress.getText().toString(), actionCodeSettings)
                    .addOnCompleteListener(new OnCompleteListener<Void>() {
                        @Override
                        public void onComplete(@NonNull Task<Void> 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();
                            }
                        }
                    });
        }
    });

Solution

This is related to Dynamic Links whitelisting and not authorized domain or continue URL whitelisting. Learn more about whitelisting dynamic links.

You need to match the pattern of the dynamic link that Firebase Auth constructs.

I already whitelisted the domain; didn't help, but thanks for the suggestion.

Sorry, I misread your comment and have since whitelisted the dynamic link (I added ^pentoapp\.page\.link/mBKw to the whitelist). Didn't help, unfortunately.

Note that I updated my original post as per the above.

@FractalBob - did you ever find the answer to this? I'm facing a similar situation: stackoverflow.com/questions/60143977/…

[FractalBob]

@AndyVoelker Yes, I did, and it was simpler than I thought: all I had to do was specify the URL of my app in Google Play and then whitelist that URL. I don't think that's going to help you, though, because you're dealing with an iOS app that works for some devices and not others. BTW, I also have an iOS version of the app and setting it up in Firebase was straightforward.
