title: Android App Link verify does not work all the time
body: <p>I am testing Android <a href="https://developer.android.com/training/app-links/verify-site-associations" rel="noreferrer">App Link</a> feature.</p>
  
  <p>I believe I have everything setup for App Link feature to work, and, yes indeed, it has worked. However, sometimes it doesn't work. I'm including logs while installing the App Link target app.</p>
  
  <p>The below is failed log</p>

  <p>The two occasions happened while installing exactly same app. Install -> delete -> install again.</p>
  
  <p>The assetlinks.json is located at <a href="https://noblapp.com/.well-known/assetlinks.json" rel="noreferrer">https://noblapp.com/.well-known/assetlinks.json</a>.</p>
  
  <p>And the test app is setup to accept '<a href="https://noblapp.com" rel="noreferrer">https://noblapp.com</a>' URL view intent.</p>
