title: How do I force an expo app to update
body: <p>I have an app written in expo, and can't figure out how to push a new build. On the expo site if I run the app from the QR code the app is correct, but the native app from the app store doesn't update.</p>
  
  <p>The steps I've been using are 
  1) exp build:android
  2) exp publish</p>
  
  <p>How do I make the app actually update?</p>
