title: Google Play Store did not ask me to create an upload keystore.....do I still have to create one?
body: <p>I am opting to use Google Play App Singing service for my app.</p>
  <p>I created a keystore, and signed my release app bundle with it. I then create an Internal Testing release, and opted in to Play App Signing with a single click. Nothing more was asked of me in this regard.</p>
  <p>Now I am confused, becuase everything I read in the docs says that you will be asked to provide an upload key for the app. I was not asked to provide this.</p>
  <p>When I go to app signing page in the Release section, it does not give me the option to upload/create and upload keystore.</p>
  <p>What exactly has happened? How I am enrolled in Play App Signing without have uploaded an upload keystore?</p>
