Notes

• LinkedIn pages change often, so selectors may need maintenance over time.
• Some filters require LinkedIn internal IDs, not display names.
• The Actor only extracts data visible to the authenticated LinkedIn account.
• The li_at cookie can expire, so refresh it when login fails or LinkedIn redirects too many times.
• If a direct post URL keeps redirecting, paste the full Cookie request header from LinkedIn instead of only the li_at value.
