How to clear previous cached urls ?

[graysuit]

First of all, thanks million. No other webview that flexible on windows.
In my app, I try to preload urls, so that they simply show up when needed.
While I see glimpse of previous url (e.g garmin), even though new url (e.g torxtrail) has been loaded and took good time needed to load properly.

Imports Microsoft.Web.WebView2.Core
Imports System.IO
Class MainWindow
    Async Sub Window_Loaded(sender As Object, e As RoutedEventArgs)
        Try
            Await InitWeb()
            NavigateWeb("https://www.garmin.com")
            Browser.Visibility = Visibility.Visible
            Await Task.Delay(TimeSpan.FromSeconds(5))
            Browser.Visibility = Visibility.Hidden
            NavigateWeb("https://torxtrail.com")         'I preloaded torxtrail site here
            Await Task.Delay(TimeSpan.FromSeconds(3))
            Browser.Visibility = Visibility.Visible
            Browser.InvalidateVisual()
            'notice glimpse of garmin first, then torxtrail ? at 00:09
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub

    Public Async Function InitWeb() As Task
        If Browser.CoreWebView2 Is Nothing Then
            Dim options As New CoreWebView2EnvironmentOptions() With {.AdditionalBrowserArguments = "--inprivate --disk-cache-size=0 --media-cache-size=0 --disable-pdf-caching"}
            Dim userData = Path.Combine($"C:\Users\{Environment.UserName}\AppData\Local\WebTest", $"{Path.GetFileName(Forms.Application.ExecutablePath)}.WebView2\1")
            Directory.CreateDirectory(userData)
            Dim env = Await CoreWebView2Environment.CreateAsync(Nothing, userData, options)
            Await Browser.EnsureCoreWebView2Async(env)
            Dim allKinds = CoreWebView2BrowsingDataKinds.AllProfile Or CoreWebView2BrowsingDataKinds.GeneralAutofill Or CoreWebView2BrowsingDataKinds.PasswordAutosave
            Await Browser.CoreWebView2.Profile.ClearBrowsingDataAsync(allKinds)
            Browser.CoreWebView2.Settings.AreDefaultContextMenusEnabled = False
            Browser.Visibility = Visibility.Hidden
        End If
    End Function

    Sub NavigateWeb(link As String)
        Browser.CoreWebView2.Navigate(link)
        Browser.InvalidateVisual()
    End Sub
End Class
