The overview tracker gives you an outline of your learners progress by displaying all your sims, and some important general information such as how many learners it has been shared to, complete/incomplete status, how many have passed or failed, or done the learn mode of that sim.
If you click on one of the rows, you will be taken to the Sim Tracker.
You can add a date range here to filter the users that have been shared your sims between those dates. Be sure to click "show results" once you have inputted a date range.
Filter users that have attempted or completed a sim within this date range.
This will remove any date filters from both the Date Shared and Activity Date fields, resulting in all the reporting data for all your users to be shown here.
