Radzen CRM Tutorial (Login not working - Urgent)

Hello everyone,

I've been testing the CRM Demo App from Radzen but I'm stuck for a couple hours in the login.
I've already debug and it's entering in the If statement (where the environment is development and the user/password is admin).

My understanding is when he tries to redirect (~/).. it goes and moves back to the login page (assuming he is trying to reach the home). The OnInitializedAsync on Home page doesn't reach.. so I still don't understand what should be the problem.

Controllers/Account Controller:

[HttpPost]
    public async Task<IActionResult> Login(string userName, string password)
    {
        if (env.EnvironmentName == "Development" && userName == "admin" && password == "admin")
        {
            var claims = new List<Claim>()
            {
                    new Claim(ClaimTypes.Name, "admin"),
                    new Claim(ClaimTypes.Email, "admin")
            };

            roleManager.Roles.ToList().ForEach(r => claims.Add(new Claim(ClaimTypes.Role, r.Name)));
            await signInManager.SignInWithClaimsAsync(new ApplicationUser { UserName = userName, Email = userName }, isPersistent: false, claims);

            return Redirect("~/");
        }

        if (!string.IsNullOrEmpty(userName) && !string.IsNullOrEmpty(password))
        {

            var result = await signInManager.PasswordSignInAsync(userName, password, false, false);

            if (result.Succeeded)
            {
                return Redirect("~/");
            }
        }

        return Redirect("~/Login?error=Invalid user or password");
    }

Login (razor):

    <form method="post" action="account/login">
    <RadzenContent Container="main">
        <ChildContent>
            <RadzenHeading Size="H1" Text="@L["pageTitle.Text"]">
            </RadzenHeading>
            <RadzenTemplateForm Action="/Account/Login" Method="post" TItem="dynamic">
                <ChildContent>
                    <RadzenLabel Component="Username" style="display: block; margin-top: 16px" Text="@L["labelUsername.Text"]">
                    </RadzenLabel>
                    <RadzenTextBox style="width: 100%" Name="Username">
                    </RadzenTextBox>
                    <RadzenLabel Component="Password" style="display: block; margin-top: 16px" Text="@L["labelPassword.Text"]">
                    </RadzenLabel>
                    <RadzenPassword style="width: 100%" Name="Password">
                    </RadzenPassword>
                    <RadzenButton ButtonType="ButtonType.Submit" Icon="exit_to_app" style="margin-top: 32px; width: 100%" Text="@L["btnLogin.Text"]">
                    </RadzenButton>
                </ChildContent>
            </RadzenTemplateForm>
        </ChildContent>
    </RadzenContent>
</form>

This issue can be closed.

After opening a new private window (w/ cache disabled) the loign worked.

Clearing all the browser cache/cookies... fixed the problem
