title: How do App bundles effect app update size
body: <p>I have an android app that is 6MB and would like to move to app bundles for adding a third party SDK as optional functionality which is 25MB. If I build the third party SDK in an app bundle I understand app download size on install will be 6MB. Once a user uses the optional feature app bundle will also be downloaded.</p>
  
  <p>My question is after user has downloaded app bundle and I send and update to the main Apk that was originally 6MB, with user already having the app bundle installed will see app update size as 6MB or 31MB</p>
