If you can't find a specific LinkedIn page to connect to Looker Studio or Sheets, chances are your role doesn't have enough permissions to connect data.
To connect your LinkedIn Pages to your Looker Studio reports, make sure the LinkedIn profile you’re connecting to Porter has super admin permissions to the LinkedIn page.
Other roles such as content admin, analyst, or even admin are not enough to pull reports from LinkedIn Pages to Google Sheets or Looker Studio.
Follow this interactive tutorial to change your role to Super Admin on LinkedIn Pages.
