In the main "category" view, there is a column "Latest" which should theoretically show the three most recently active topics in that category. Like in the "Latest" view itself, the pinned posts show at the top. However, unlike in the "Latest" view, when you unpin a post, it STILL stays at the top of the category view. In other words, unpinning a post doesn't work.
Here we see my current view of the Walt Disney World category. I have unpinned all three of those pinned topics, as is evidenced by the push pin icon pointing to the side rather than down. Yet, they're all still showing up there, blocking the view of the three topics that are actually the latest. This is highly annoying. I really hope Discourse will fix it. @daybreaker @LaurelStewart any chance?
