Survey theme/template:
==================
Since last week we are having problems with a survey that we display through an iframe on another domain.
The error (attached image) appears in the Safari browser and in incognito windows in both Chrome and Safarihttps://ibb.co/cvWhc9nhttps://ibb.co/cvWhc9n. In Chrome browsers it is displayed correctly.

We activate the option 'Embedded IFrames are allowed' and 'Force HTTPS' in the Security section of the global configuration and add the following code:

'session' => array (
'sessionName'=>'LS-VBXZZORFJZCAKGYI',
// Uncomment the following lines if you need table-based sessions.
// Note: Table-based sessions are currently not supported on MSSQL server.
// 'class' => 'application.core.web.DbHttpSession',
// 'connectionID' => 'db',
// 'sessionTableName' => '{{sessions}}',
'cookieParams' => array(
'secure' => true,
'httponly' => true,
'samesite' => 'None',
),
),

'request' => array(
'enableCsrfValidation'=>true,
'csrfCookie' => array(
'sameSite' => 'None',
'secure' => true,
),

Which we saw in the manual

We don't know what else to do.from the safari browser itself by disabling the "prevent cross-site tracking" option in the preferences > privacy section no longer causes this problem. But I need a solution in the code so that this does not happen because I cannot control who accesses safari and make everyone perform this option
 Thanks for the help
