Posting to LinkedIn company pages
Publish as a company page you manage, not only your personal profile.
Posting to LinkedIn company pages requires Pro. When you connect LinkedIn, SparkVox loads company pages you administer. Enable the pages you want under Settings → Integrations → LinkedIn (checkboxes next to each identity). Enabled pages then appear in the channel selector in the post editor.
Choose your personal profile or a company page before scheduling. Your selection applies to that post only; you can switch channels for other drafts. Use Refresh company pages in Integrations if a new page does not appear yet. If schedule or publish fails with a permission error, ask a LinkedIn page admin for posting access or switch to your personal profile under Post as.
