LinkedIn has strict limitations on how posts and insights are available for you, especially for personal LinkedIn accounts. For business purposes, you should create a LinkedIn business page to see insights and more.
Posts published to your LinkedIn personal account do not have insights (likes, shares, views, etc).
However, posts published to LinkedIn Business Pages have insights.
Due to LinkedIn limitations, you cannot see insights for your personal LinkedIn account in the statistics view.
Is your LinkedIn connection alive?
Unfortunately, sometimes the connection to your LinkedIn Business Page account is expired and thus the insights are not visible anymore. To fix that, try to reconnect the account.
