title: Application crashes on update from app store
body: <p>I have a app working fine and it is already submitted to app store. Now the problem comes in when the users of my app try to update the app with the latest version from the app store. The app crashes at splash screen.<br/>
  If they delete the old version and make a fresh download then it does not pose any problem.<br/>
  So what could be the factors causing this problem ?</p>
  
  <p>Thanks in advance.</p>
