Flyout not working

I installed the plugin on a separate site, with all the same settings as the previous one (both in development servers, so no public link available currently). For some reason, the flyout isn’t working.

What’s the best method to troubleshoot why the flyout isn’t triggered? I’m currently going through disabling other plugins to see if there’s a conflict in there, but wanted to see if there’s a console command I can issue in a browser that would give me any additional information on it not being triggered?

When I add to cart, the cart icon doesn’t show (unless I refresh), so there’s something not working right on the DOM.

Just thought I’d ask here if you have any thoughts.
