Activity is only recorded when a prospect interacts with the link that you shared. If the link points to a video as an example we can also tell you how much of the video the prospect watched. For tracking to work you must send the resource from the contact card in the app so we can track it back to one prospect.
If you don't see activity:
Confirm the resource was sent through the contact's profile.
Ask the prospect if they opened the resource.
Allow a few minutes for engagement to synchronize.
Remember, sending a resource doesn't automatically create activity —your prospect must interact with it for you to get credit for an engagement and engagement only happens when a unique prospect engages for the first time with information you sent. Engagement is also how points are earned on a leaderboard.
