Settings — LinkedIn Connection
This system connects to exactly one LinkedIn account at a time. Connecting a different account replaces whichever one was connected before.
Organization (company-page) publishing needs LinkedIn's Community Management API, which requires Partner Program approval — see README.md for how to apply. Until approved (or if the connected account doesn't have it), post drafts are published via the personal-profile API and everything else is sent manually and logged via "I sent this manually" in the Approval Queue.
