title: How long for Firebase Remote Config to push?
body: <p>How long does it take for a remote config to push? I have the following code, which continues to print false and the old value for at least a few minutes after pushing a new update on the web.</p>
  
  <pre><code>remoteConfig.fetchWithCompletionHandler { (status, error) -&gt; Void in
      if (status == FIRRemoteConfigFetchStatus.Success) {
          print("Config fetched.")
          print(self.remoteConfig.activateFetched())
          print(self.remoteConfig.configValueForKey("my_key").stringValue)
      } else {
          print("Config not fetched.")
      }
  }
  </code></pre>
