title: Why did SafetyNet Attestation stop working?
body: <p>I have an app which has been using the <a href="https://developer.android.com/training/safetynet/attestation" rel="noreferrer">SafetyNet Attestation API</a> for some time.</p>
  
  <p>All of a sudden, all calls to the API started failing. Did something happen to the SafetyNet Attestation API?</p>
