CSRF

I am working on a old project in CI3.
Added a form and enabled csrf protection.
For chrome and firefox, the form gets submitted and it’s working well. But for safari
It’s showing “ The action you have requested is not allowed.”
i set $config['csrf_regenerate'] = FALSE;

Safari generate new token every time i refresh the page.

3rd party cookies also enabled in the settings.

Any idea?

Thanks!
