User blog comment:Gilgameshkun/Realignment of Template:Teen/@comment-3090219-20190822200950/@comment-3090219-20190822211753

However I have noticed that both templates (Teen and Mature) don't seem to appear visible within the articles when these are visited from mobile devices (at least not in mi case using my Android phone or Wikia's Mobile Preview when editing), in the regular expirience of course, outside of the 'Desktop' view mode option.

Since that is possibly the main medium by which users navigate through this wiki now days (unaware of the existence or use of the 'Desktop' view mode option), this would affect the fundamental purpose of such templates, since there is a high possibility that almost ALL users will not even notice these preventive notifications due to this apparent visual incompatibility.
