This issue is tied to LinkedIn's API permissions and privacy model. LinkedIn restricts access to certain company-related data via its API. Only designated Admins have the authorization to retrieve and display a company's feed through the API. If a user is not a designated admin, even if they are logged in, they don't have the necessary permissions to view that content programmatically.

In essence, LinkedIn’s API ensures that company updates are protected and only accessible to users who have been explicitly granted admin rights. This is a data privacy and control measure to prevent unauthorized display or misuse of corporate content.

What you can do:

Admin-only wall display: If your SharePoint is internal and the goal is for employees to see curated LinkedIn content, consider using a third-party aggregator that doesn’t require each user to be an admin. Tools like Walls.io offer a way to display your LinkedIn company posts (along with public hashtag content and content from other platforms) in a centralized feed embeddable in SharePoint or intranet. Since it’s GDPR & CCPA-compliant and offers content moderation, it works well for internal comms and avoids the admin access problem altogether.
