Pinning a post - what happened?

There was no recent change around that area.

To unpin a pinned post, press the "Unpin" button of the sticky Post located in your profile (without clicking to open the post page).

You are only able to pin five posts at once. As you have already done that you’ll need to unpin an older post before you can pin a new one.

I just now unpinned a post and pinned a new one. Worked for me.

I don't see the option ,either but there a limit to how many posts you can pin📌

Just go to the store and buy a box of pins....Its that easy

I've never had the option or been able to find it 😒
