I’m getting this warning on the browser console for my Wordpress site.
A cookie associated with a cross-site resource at https://www.google.com/ was set without the SameSite attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with SameSite=None and Secure. You can review cookies in developer tools under Application>Storage>Cookies and see more details at Chrome Platform Status and Chrome Platform Status.
I tried to fix the problem by adding the following codes to the child theme functions.php file, but nothing happened. I believe I am missing something, maybe an code opening or something else since I am not a PHP expert.
