Hustle performance issue with PHP sessions

Hi,

I see, you are using PHP sessions for the popups. It is not recommended for a lot of reasons, which are detailed in these articles:
https://wpengine.com/support/cookies-and-php-sessions/
https://pressjitsu.com/blog/wordpress-sessions-performance/

Can you please check your plugin and change PHP sessions to cookies, if it is possible and make sense?

Thank you!
