Changing Session cookie - samesite v4.6.1

Hi all,
Using v4.6.1 - in app/Config/Cookie.php - after changing samesite setting to 'None'

PHP Code:

    public string $samesite = 'None'; 


Console error is:

Cookie “pm_id” has been rejected because it is in a cross-site context ...

Still get cross-site errors. I'm doing this for testing, connecting to the remote CI4 server from localhost on local machine.

I've tried using Cookie helper to no avail-:

PHP Code:

helper('cookie');
 set_cookie('session_id', '', 3600, '','', true, true, 'None'); 


Is it possible to force samesite to 'None' for the CI session cookie?

Many thanks,
Mike

Just to confirm, are you the one setting up the cookie named "pm_id"? From your example, it seems the name is "session_id".

Confirmed: whether using 'session_id', or 'pm_id', the issue remains the same.

I believe this is a bug. Any setting in Cookie $samesite appears to be overridden by the default Lax setting.
