I recently published my site and someone shared it on Facebook. When I visit my site via the link from facebook, my “back to top” in-page link feature (which sends the user to the top of the page section) is dead. It works normally when visiting the site directly. I also noticed the same problem when visiting my site from my own facebook profile.
You can see for yourself by comparing both links:
(FACEBOOK SHARED LINK) - dead feature
(LINK FROM FACEBOOK PROFILE) - dead feature
(DIRECT LINK) - working feature
The affected in-page link is at the very bottom of the website (“back to top”)
Any investigation would be great!
