Firebase-Invite Dynamic Link Unity iOS - Dynamic link opens the App, but can't retrieve the content of the link

Question

I've finally succeeded on implementing the dynamic link (manually created and the shortened by the Rest API), that works fine and opens the game when clicked.

The thing is, once opened, I can't retrieve anything from it. I've copied the example code from the documentation, added some logs, and nothing.

Here is my code,

// When the app starts, check to make sure that we have
// the required dependencies to use Firebase, and if not,
// add them if possible.
void Start()
{
    dependencyStatus = Firebase.FirebaseApp.CheckDependencies();
    if (dependencyStatus != Firebase.DependencyStatus.Available)
    {
        Firebase.FirebaseApp.FixDependenciesAsync().ContinueWith(task => {
            dependencyStatus = Firebase.FirebaseApp.CheckDependencies();
            if (dependencyStatus == Firebase.DependencyStatus.Available)
            {
                InitializeFirebase();
            } else
            {
                Debug.LogError("Could not resolve all Firebase dependencies: " + dependencyStatus);
            }
        });
    } else {
        InitializeFirebase();
    }
}

// Set the listeners for the various Invite received events.
void InitializeFirebase()
{
    Firebase.Invites.FirebaseInvites.InviteReceived += OnInviteReceived;
    Firebase.Invites.FirebaseInvites.InviteNotReceived += OnInviteNotReceived;
    Firebase.Invites.FirebaseInvites.ErrorReceived += OnErrorReceived;
    Debug.Log("Invites initialized");
}

void OnInviteReceived(object sender, Firebase.Invites.InviteReceivedEventArgs e)
{
    Debug.Log ("OnInviteRecieved");
    if (e.InvitationId != "")
    {
        Debug.Log("Invite received: Invitation ID: " + e.InvitationId);
        Firebase.Invites.FirebaseInvites.ConvertInvitationAsync(e.InvitationId).ContinueWith(HandleConversionResult);
    }
    if (e.DeepLink.ToString () != "")
    {
        Debug.Log ("Invite received: Deep Link: " + e.DeepLink);
        PrepareLevel (e.DeepLink.ToString ());
    }
}

void OnInviteNotReceived(object sender, System.EventArgs e)
{
    Debug.Log ("OnInviteNotReceived");
    Debug.Log("No Invite or Deep Link received on start up");
}

void OnErrorReceived(object sender, Firebase.Invites.InviteErrorReceivedEventArgs e)
{
    Debug.Log ("OnErrorReceived");
    Debug.LogError("Error occurred received the invite: " + e.ErrorMessage);
}

void HandleConversionResult(Task convertTask)
{
    Debug.Log ("HandleConversionResult");
    if (convertTask.IsCanceled) {
        Debug.Log("Conversion canceled.");
    } else if (convertTask.IsFaulted) {
        Debug.Log("Conversion encountered an error:");
        Debug.Log(convertTask.Exception.ToString());
    } else if (convertTask.IsCompleted) {
        Debug.Log("Conversion completed successfully!");
    }
}

And here is the logs I get from the device (iPhone6S).

Also, "Invites initialized" has been prompted, and the object still exist when the app is opened from the dynamic link (it's never destroyed).

Oh, and I oppened the link via facebook messenger app.

All help will be greatly appreciated.
