Cleaning Solution Dispenser

I've added cleaning solution to the dispenser but it isnt adding any during the mopping process. It's still completely full. Is there a setting I need to turn on to tell it to add the cleaning solution?

On your main app page click on go. On the bottom right you will see the words dock and click on that. Once you click on that you will see dock settings and click the toggle switch for auto detergents dispense. That should do the trick.
