title: iOS launch screen does not update
body: <p>I've updated launch screen on an enterprise app, but it won't update when installed on an iPad with the existing app. I've tried completely deleting the app before installing a new version, but it still launches with the old launch screen image.</p>
  
  <p>I've tried installing the new app on another iPad where this app was never installed and the new launch screen appears as expected. Both iPads run the same iOS v9. The app was built with xCode 7.2</p>
  
  <p>In summary I've tried the following scenarios:</p>
  
  <ol>
  <li><p>updating existing app (version 1) on iPad A - with a new app (version 2)
  iPad A, loads the new app v2 with launch screen from version 1</p></li>
  <li><p>installed new app (version 2) on iPad B, which never had this app.
  iPad B, loads the new app v2 with correct launch screen
  then I installed old app version 1 on iPad B
  iPad B, now loads the old app v1 with launch screen from version 2</p></li>
  </ol>
  
  <p>It seems the iPad somehow caches the launch screen from the very fist install regardless which version it is. Deleting the app and reinstalling does not seem to help and it does not look code related as the correct launch screen images was loaded on iPad B</p>
