In order to save you time by only loading the data that you need, your tracker minimises the unit you currently have open when you go to open a different one by default.
However, sometimes it's necessary to review all of the data on your tracker at the same time, so you can easily override this to show multiple units at the same time.
To enable multiple units to show on your tracker:
Open View in the left menu.
Under Multiple units view, select Enable showing multiple units.
Click Yes to confirm the popup message.
Click outside of the View menu to return to your tracker.
Expand (+) as many units as you wish to view.
💡 Tip: Enabling showing multiple units can result in slightly slower loading times from your tracker, due to loading much more data at once. For this reason, we'd recommend completing the same steps to disable showing multiple units once you're done reviewing data.
