Hi guys, I have the same problem.
Chrome will only accept SameSite=None if it is paired with the secure header.
The cookie must be served over HTTPS, so make sure your website handles any HTTP redirection as required.
I find a solution for me, in the config.php I changed that line:
$config['cookie_path'] = '/';
to this one:
$config['cookie_path'] = '/; SameSite=None';
It works for me.
