Weird. You may want to try re-building them. And make sure Elementor is upgraded to recent version. It is hard to put my finger on what’s happening here. For instance, I tested it in Firefox and at first didn’t work. Then, suddenly, a popup showed up after a minute or so and now they all work. I am getting some warnings in Inspector about cookies. I’m wondering if there’s some kind of conflict here with other JS code which is dropping cookies, such as Facebook or Analytics.
