Or not.
I deactivated all of the plugins except for Elementor and Elements Plus. I tried both with Elementor Pro activated and deactivated. I tried changing the theme to Twenty-Seventeen. I tried starting a new page with new sections and text. The schedule still seems not to work on sections. I also tried installing Elements Plus on my local machine and the section schedule wasn’t working on there, either.
Two questions:
1) What theme are you using?
2) Could there be some other part of Elements Plus that needs to be enabled for the schedule to work on sections? I have only enable Schedule since that is all I need.
