When I was making my profile page with Impactstory they could not find any publications associated with my ORCID. Then I got information about that I could send Scopus my details and my publication list to ORCID. It is done throught the tool Scopus ORCID importer wizard.
I also did make a tutorial about how to give Scopus permission to read your ORCID record. Scopus needs a permission to find authors profiles in Scopus and send the author Scopus ID to ORCID.
