Hi,
Did you set your device as test device?
There can be many things wrong, maybe you accidentally changed something.
if you need to test on a device, you can add a text to your canvas and place some "ugui text set text" in the states it should pass,
for example place 1 in the state where 'show ad' is and set the text to "show ad state" then on the next state place 1 with the text "show ad Done" and so on.
if it goes to fast you can add some wait actions.
