Hello Tom,
I am really sorry for the delay of this reply as it is a weekend for us here. Can you please edit your LinkedIn app and ensure that the permissions shown here are also checked?

If it wasn't checked, check it and save your app. Then revoke and re-authenticate again.
If the problem still persists, can you please edit your first post to include the site and linkedin access so that we can troubleshoot this?
