After activating the autoptimize in my site, I came across an issue about the off canvas menu. In some specific pages it appearing bellow the footer and the menu it self doesn’t work on mobile version. Here is the list of the pages:
I’m experiencing exactly the same problem, however I don’t have Autopimize.
I have an empty menu assigned as Primary menu and a menu assigned to Canvas.
The hamburger icon doesn’t work on both mobile and desktop, and the canvas menu appears below the footer (on all pages).
