Use this URL if you only want to view just the group activity of your LinkedIn connections (which connections joined a group, who started a discussion, who commented on a discussion, etc.). It’s a handy way to get current on your connections’ group activities.

LinkedIn provides a number of ways to sort and view your own and your connections’ activities, filtering out what you don’t want to see, including this URL to view all the shares, likes, and comments your connections have recently made.
Both of these URLs are valuable if you want to check in and see what your groups have been up to and continue interacting with them through likes, comments, or posts of your own.
