The activities feed on a candidate or contact record doesnt show WHO did this activity. That is very important for our business so we know who is the last person who spoke to them. Can you add that in to be visible please?
If one user has been involved with multiple past activities, their user will be listed on the top activity in the feed that was last associated with them. We have received some feedback on this regarding adding their user to all activities in the feed, so it is something we are taking into account on updates going forward.
