I added that code to the correct .sortable() call in acf-pro-input.js and yes, you can move elements between flexible content containers now, but when saving, the element that was moved gets deleted from the page entirely.
When I inspect the DOM, I see that the element that was moved has the same data-id as another element in the container that it was moved to. I’m guess that’s the conflict here.
Help on this one would be killer. Thanks!
