So I've gotten the Adobe Draw app a couple times actually. I always deleted it because I didnt even know to start/create a drawing. How do you start a drawing?
Once you launch it, and click the "+" button, you'll see a few panels in a new project, populated with 5 drawings.
Pick any one of those boxes by clicking on it, then start drawing.
There are many features in Draw, but all you have to do is start drawing with your finger.
There's a bunch of online help here for more:
The best part is that you can send your drawing to your CC2014 account and open it in Photoshop or Illustrator
