Why isn't smoke appearing when I add quick smoke?

I followed this tutorial step by step but when i got to @3:26 the smoke doesn’t appear at all. I checked I am in cycles

Έχεις πατήσει play να παίξει το animation μια φορά πριν κάνεις render ;(press space to play the animation once and the second time smoke shows up for me, except in cycles the result looks awful).

I found out whats wrong, by default the smoke is invisible in render
