Dicourse 2.4 made muted categories visible by default, however our forum uses a CSS modification to keep the old behavior.
I’m not sure what would be best for our forum to either make a muted category hidden on both desktop and mobile or disable the CSS modification for desktop.
It’s definitely an issue with the component then. This has been around for quite a while so it’s definitely noticeable. Hard refreshing on Safari and Discourse App did not fix the issue. I’ll update the my post on meta with these details.
