title: Firebase Remote Config Force Refresh on Update
body: <p>I recently added Firebase remote config to my project in order to manage some app settings remotely.</p>
  <p>Due the nature of Firebase, the configs can only be updated on client side every 12 hours. And as I added the variables to the remote config slowly, I accidentaly created the following scenario:</p>
  <ol>
  <li>User has version A of the app with few variables on remote config.</li>
  <li>App updates variables from firebase</li>
  <li>User updates app version to A+1 which has new variables on remote config</li>
  <li>App tries to update variables from firebase but is denied due to short request interval.</li>
  <li>App is running with the new variables all set to &quot;&quot; until firebase allows remote config update</li>
  </ol>
  <p>Is there any way to force Firebase to update the remote config fields on update?</p>
