Since when is it no longer allowed? It worked just fine until recently and it’s still listed as acceptable text formatting code here: https://forum.inaturalist.org/t/useful-html-tags-for-inaturalist-comments-and-other-text-wiki/6198
I’ve got 3,000+ observations, many of which use that tag in the notes, and I just don’t have time to go through all those to change it manually. I will never find all my comments that use the tag to italicize species names on other people’s pages. I’m sure I’m not the only one affected. If this is by design, I think it would be nice if someone could run a script or something to change all those old tags to whatever it should be now so it displays as intended. As we probably all know, species names should be in italics.
