This is embarrassing, but I have been confused about how to pin posts in Peakd.com. I have been able to pin some posts, but not every time I was successful. I've been meaning to ask someone but just hadn't got around to it.
So, it appears that you first have to 'unpin a post' before you can pin a different one. I am so used to how Twitter works (with just pinning a different one without having to 'unpin a tweet'), that I just assumed peakd.com would work the same. NOT. LOL. 😂
Anyway, i think after months of being confused, i figured it out.
lmao.
