.NET MAUI Setting an item SelectedIndex on Page Load is Delayed

When the view appears on the screen there is a short delay setting the values to each control. Is it possible to set the values before the user sees the view?

public UserSettingsView()
{
    InitializeComponent();
    LoadAsync();        
}

private async void LoadAsync()
{
    try
    {
        // Loading data from API
        Languages = await _languageService.GetAsync(AccessToken);
        USStates = await _uSStateService.GetAsync(AccessToken);
        
        // Assigning the list to the ItemSource of each Picker.
        ddlLanguages.ItemsSource = Languages;
        ddlUSStates.ItemsSource = USStates;

        // Getting the user's preferred settings
        var userSettings = await _accountService.GetSettingsAsync(UserID, AccessToken);

        if (userSettings != null)
        {
            // Setting user values to each Picker control. 
            // This is where the delay happens.
            ddlLanguages.SelectedIndex = Languages.FindIndex(x => x.ID == userSettings .LanguageID);
            ddlUSStates.SelectedIndex = USStates.FindIndex(x => x.ID == userSettings .USStateID);
            cbAge.IsChecked = currentSettings.AgeQualified;
        }
    }
    catch
    {
        await DisplayAlert("Oh no!", "Error loading the page", "OK");
    }
}
