On 7/25, the pinned link feature will be removed from Campsite. This was not an easy decision, but we've had a lot of issues that have been hard to solve since it's introduction.
In it's place, you can use our add link in place button. This can accomplish the same thing as pinning your links, by avoiding having to shift things around when adding a new one.
Let us know if you have any questions and thanks for your understanding.
