title: How to get updated remote config values after setting user properties
body: <p>I'm currently running an A/B test on a remote config value in Firebase. The target of the test is for users with a user property X that is contained in a regex.</p>
  
  <p>My problem is that I fetch the remote configs for the user BEFORE setting the user property, so I need to update the remote config when the user property is set. So basically, a force update of a remote config (that is updated because the user is now part of the AB test).</p>
  
  <p>Any ideas?</p>
