Having already done a review of Elementor Under Duress just 2 months ago, it hardly seemed timely  to do  another More Elementor Duress. But having tried to create a container with attached Motion Effects and then an Elementor Popup – both  using the new Elementor 3.72 with full Flexbox container implementation abruptly changed plans. There is a slight problem creating a Popup with elementary styling – it turns out to be Mission Impossible. Here is the proof:
Every container object failed to display both  Style and Advanced CSS/JavaScript options. The net result was the need to use a different Popup plugin to fill in the gap.
