title: expo build (IOS & android) and Expo publish error
body: <p>I've been trying to build an app I was working for for the last month, but it doesn't want to work when I use the commands:</p>
  
  <p>expo build:android
  expo build:ios
  expo publish
  But my app runs normally on development mode, on both real android and IOS devices</p>
  
  <p>Samsung galaxy s8
  Iphone 9s</p>
  
  <p>with no errors or anything.</p>
  
  <pre><code>expo build:android
  Checking if there is a build in progress...
