There is no clear reaction when I press the button to start cleaning.
The moment I tap the button, I think it would be nice if the button flips or changes color.
The status text (just below the robot name) should change to 'I am cleaning', when you press the button.
A lot of times the severe lag in the app causes there to be no change. If you leave the app and come back in it'll refresh.
I have the same experience with the map.
