If you zoom out too far or pan away from the Stage it can look like the Stage has disappeared. This is easily remedied using the quick-pinch gesture to fit the Stage to your screen.

Check out the Gestures page of the Procreate Dreams handbook for a demonstration on how to quick-pinch.

If you still can’t see the Stage:

1. Tap the Theater icon on the far left of the main toolbar to exit your movie.

2. Tap the movie in Theater to re-open.
