title: Android app says it is not optimized after changing to app-bundle mechanism
body: <p>Just changed my app-delivery to the new bundle-mechanism and now it shows "app not optimized" for tablets (tested with Google Pixel C and some 7" Lenovo Tab).</p>
  
  <p>Could it be, because I only have sw600dp for handling tablets and nothing higher (sw720dp or sw1024dp)?</p>
  
  <p>And is there a way to determine which device is optimized for my app and which not?</p>
