Hi, I'm trying to create a cookie in a surface controller with following code:

public IActionResult SaveCookiePreferences(CookiesConsentViewModel model)
    {
        if (!ModelState.IsValid)
        {
            return CurrentUmbracoPage();
        }

        var cookieOptions = new CookieOptions()
        {
            Path = "/",
            HttpOnly = false,
            IsEssential = true,
            Expires = DateTime.Now.AddYears(2)
        };

        Response.Cookies.Append("cookiename", "cookievalue", cookieOptions);

        return CurrentUmbracoPage();
    }

When the page reloads, and I read my cookie it is not set. But when I reload the page again. The cookie exists and has the correct value.

What could be the issue here?

In our v8 .NET code I remember setting both Request and Response cookies like this:

HttpContext.Request.Cookies[CookiesConsentCookieKey][ExplicitConsentCookieKey] = bool.TrueString;
HttpContext.Response.Cookies[CookiesConsentCookieKey][ExplicitConsentCookieKey] = bool.TrueString;

But .NET core only allows setting Response cookies.

Thanks for any advice!
