title: Using Firebase App Check is not working (debug)
body: <p>I am not able to settle this issue when implementing the new App Check feature from Firebase.</p>
  <p>When uploading files to Firebase Storage it fails with an error</p>
  <blockquote>
  <p>Caused by: java.io.IOException: {  &quot;error&quot;: {    &quot;code&quot;: 401,    &quot;message&quot;: &quot;Firebase App Check token is invalid.&quot;  }}</p>
  </blockquote>
  <p>I already provided the debug secret just like what is in this <a href="https://firebase.google.com/docs/app-check/android-debug-provider?authuser=0" rel="noreferrer">documentation</a>.</p>
  <p>The debug apk was installed directly via USB debugging.</p>
  <p><strong>Note:</strong>
  I am using a physical device and enabled <strong>Enforce</strong> status on both <strong>Storage</strong> and <strong>Real-time database</strong> and it fails whenever I tried to do transaction like upload and the error above shows.</p>
