I have built several websites with the approach to show/hide fields based on a existing switch.
I use it on multiple sites, and has always worked fine. Yesterday I noticed it stopped working on one of them (I had just updated metabox AIO to 1.30.1). I went to another site, which was still on 1.30.0 and everything was working on my site. Just to be sure it was the update, i updated this second site to 1.30.1, and, voilá, all switches conditional logic stopped working.
If a fix is not possible for now, I would like to go back to 1.30.0.
