Frozen Header Stopped Working

My floating menu stopped working today. Looks like they must have done some global platform updates or something…?? Anyone else using a frozen header experiencing this?

My menu has been set up like this Wix video tutorial for some time without issues: https://www.youtube.com/watch?v=8iO0G_qWqRY
