ACTIVITY SECTION

You can view your posts or another LinkedIn member’s posts, articles, and profile activity from the Activity section of your profile page.

However, suppose you don’t see any activity in the Activity section of a member’s profile.

In that case, the member may have set their settings to private, or they may not have any recent activity.
If you haven’t had any activity on LinkedIn for 90 days, your Activity section will be hidden from your profile.

Any specific actions to take in your Activity section will be listed in LINKEDIN best practice.
