Thanks Waqas, I first tried to go back to 3.0.0, but no luck. I now went back to 2.9.9 and things are back to normal. Much appreciate your feedback!
Waqas’s video is exactly what I experience. Its a mess
I have similar problems, the UI is hardly workable anymore. Cannot delete sections and columns, then it deletes sections when I delete a column. After every change you need to save as draft and then reload page to see what elementor decided to do.
Rerun Update Script makes no difference.
Astonishing that Elementor can release something that is so broken.
