"HUSTLE" PLUGIN NOT WORKING on https://beinart.org

I have "Hustle" active on my wordpress website (beinart.org) but my timed mailchimp popup is not working. I have set it to be triggered after 25 seconds, but it won't popup. I have had it styled perfectly for my website and even have it popping up via a button, but the timed 25 second popup is not working. It would be greatly appreciated if you could look into this and fix this for me. I have granted support access on my website via the wpmudev support plugin. Thank you!
