title: Updating an APK in Google Play without changing the expansion file
body: <p>I have a "draft" APK in my Google Play console, and it's connected to an APK expansion file.
  The version code is 9, and the expansion file is "main.9.com.something.something.obb".</p>
  
  <p>Now, I'm trying to update the APK before I release. I increased the version code, along with some code changes.
  When I upload the APK, I choose to use "main.9.com.something.something.obb" as my expansion.</p>
  
  <p>Now, Google Play tells me this:</p>
  
  <blockquote>
    <p>This configuration cannot be published for the following reason(s):
    Version 9 is not served to any device configuration: all devices that
    might receive version 9 would receive version 10.</p>
  </blockquote>
  
  <p>But if I try to delete version 9, it won't let me, because it says that there are other versions depending on its expansion file!</p>
  
  <p>So it's an infinite loop and I can't update my APK. The only solution I found is to re-upload the APK expansion (400MB), which is unacceptable. I don't want to do this every time I update the app, because users will need to re-download the expansion.</p>
  
  <p>Also, I'm almost sure that this was never like that, and it's a bug that got introduced in the last period. I remember APK options like "deactivate" and so on, and now I can't find them.
  Any help?</p>
