Popup Not Closing on Submit Mailchimp Form

Hello,

Everything about this plugin is great, but I have one glitch that’s preventing me from using it. The popup does not close upon submit of my Mailchimp opt in form. I have tried it with every combination of Form Submit setting and Popup Loading Method (though I get a warning that the Footer method is not compatible with my theme.)

Here is a sample with the Form Submit setting of “Always close after form submit” and the Popup Loading Method of “WordPress AJAX”: https://www.waschmidtgraphics.net/wucker_live_site_backup/writing/

When I click submit, I’m taken to the Mailchimp Confirmation page in a separate tab, but the page I left still has the popup open on it. Does the closing on submit not work with Mailchimp forms?

Thank you so much.
