Query.observe doesn't seem to fire

[CLynch99]

I'm not quite sure what is going on, so I would appreciate any recommendations. I am trying to update businesses to the screen as the user walks down the street (through the emulator). The businesses appear as the user is in close proximity, but the exit query doesn't seem to fire when the markers are out of proximity. I'm not sure why this is the case. Also, if you have any recommendations for what I should do I would appreciate it.

  `    
  let geofireRef = Database.database().reference()
  let geoFire: GeoFire

  var businessAnno = [String:MKAnnotation]()

  var annotations = [MKAnnotation]()

  init(_ control: MapView) {
          self.control = control
          self.center = control.center
          self.geoFire = GeoFire(firebaseRef: geofireRef.child("business_locations"))
  }

  func mapView(_ mapView: MKMapView, didUpdate userLocation: MKUserLocation) {
          setupListener(mapView)
  }

  func setupListener(_ mapView: MKMapView){

    let query = geoFire.query(with: MKCoordinateRegion(center: center.coordinate, latitudinalMeters: 250, 
    ### ### **longitudinalMeters:** 250))

    query.observe(.keyEntered, with: { (key: String!, location: CLLocation!) in
        print("Enter: \(key!)")
        let annotation = MKPointAnnotation()

        annotation.title = key
        annotation.coordinate = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: 
        location.coordinate.longitude)

        annotations.append(annotation)
        mapView.addAnnotation(annotation)

    query.observe(.keyExited, with: { (key: String!, location: CLLocation!) in
        print("Exit: \(key!)")

    query.observeReady {
        self.annotations.append(contentsOf: annotations)
    }
}

} `

I'm having the same issue. It seems to fire ok when initially loading, then it when I pull another view above the Map and then minimize it seems to stop, .observe still keeps working though.

UPDATE: This seems to be a timing problem??? when initially loading the screen it doesn't work. However, after some time it works the way it should? Connor are you experiencing the same or have any progress?
