@Katharsisdrill I think you have to search it in your timeline.🙁
It would be nice if they could just be unpinned on the main page or had an icon, that showed wich toot was pinned. 🤔
Visit your own profile, and click your avatar. This will open your 'web view', and from there you can see your pinned toots on top. Click the time/date of the pinned toot to view it, and then click 'open in web'.
From there you can unpin it.
It's a bit circuitous, but it'll locate those toots quickly.
@NFG - Thanks... that did it - still room for some design improvements it seem :)
I've just been reliably informed that there's a quicker, though still somewhat unintuitive way to do this:
getting started (the default view) and 'pinned toots'.
