Naboo - Why doesn’t the recipe start when I select it in My Nabook?

My Nabook holds the recipes present in the Device.

To activate the recipe it must first be selected, then it must be moved to the “Homepage” using a box that will appear in the bottom centre of the screen.

Once the box appears, drag the recipe to it. The box will turn blue and then release the recipe, which will then appear immediately in the home page.
