Hello. We are using your popup on Search Engine Journal https://www.searchenginejournal.com/ and there is a problem with that.
Your plugin codes are written not efficiently. If you look into console tab "Network" then you will see that your plugin does Ajax call every time when page is loaded. Even if one closed popup before ( and condition of "Close" button acts as "Never see this message again" is checked) it does useless Ajax request by overloading server for that visitor.
This means that you don't perform cookie check before doing Ajax call and do check after Ajax is completed.
Can you please fix it in the next versions of plugin so whoever closed popup you do cookie check then do Ajax call?
