So reordering pinned posts is not possible. Also, on my host and my host only @-mentions in one pinned post are completely messed up (as in I type my
mastodon.social
address and it links my now-defunct isurf address), as is the cw for that post. Also, on mobile in portrait mode the pinned icon doesn't work. I instead tend to check whether something is someone's pinned post by its age.
