Yes. Timeline Managers can pin and unpin content on any Timeline they manage, while Hub Moderators can do so within the Hubs they moderate. If you don’t have the required permissions, the pin post option won’t be available.
To pin content, click the three-dot menu next to the post and select Pin post. It will remain at the top of the Timeline until unpinned. There’s no limit to how many items can be pinned, and where there are multiple, they are ordered by publish date.
System, recognition, and user posts can all be pinned, but this feature isn’t available on personal Timelines.
When a Hub is used as a content source for another Timeline, its pinned content will also appear at the top of that Timeline. Everyone with access will see the same pinned content in the same position.
