During the recent Canvas upgrade this summer, there appears to be some type of glitch that randomly adjusted my discussion settings.  Specifically, on about 2/3 of my discussions in each class- it has them listed as "Disallow threaded replies."  In the decades that I have taught online, I have never clicked this button, but now it appears I need to manually change this setting in about 18 different discussions questions in EACH of my courses.  (Discovered this after rolling over content from multiple courses!) Hours of work unless one of the amazing Canvas Gurus on here has a quick way to edit this particular setting in every discussion post within a course?
