title: Using Firebase App Distribution service is resulting in app not installed error
body: <p>I'm using the <a href="https://firebase.google.com/docs/app-distribution" rel="noreferrer">Firebase app distribution service</a> for the Android platform. For automatic distributions, I've set up the Gradle file according to the steps mentioned in <a href="https://firebase.google.com/docs/app-distribution/android/distribute-gradle" rel="noreferrer">the docs</a>. The setup and auth are successful. The distribution is also successful. But once I download the app using Firebase's App Tester app for Android, it results in app not installed error. This is for both: debug as well as release variant.</p>
  
  <p>I tried installing the app after disabling the Google play protect, but the issue remains. Can someone please help me regarding this?</p>
