@Facer_Official I had a situation where I was trying to switch on Inspection for a face that had already been published with Inspection disabled. Updating with the option checked does not enable Inspection as desired. I believe this is a bug.
What finally did work was using the drop-down option to enable Inspection before opening the watch face for edits in Facer Creator.
P.S. Insidious was the watch face in question.
