I'm using the MKMapViewDelegate methods with SwiftUI and adding annotations mostly work as long as there are no image customizations. If I try to change the color or flip the image only the standard image is shown. Using the debugger I can see that the annotationView.image in memory is correct (when parent.routeMeta.headingLeftToRight is false), yet the map displays the standard image. Any suggestions?

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
              let annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "TempAnnotationView")
              annotationView.canShowCallout = true
              annotationView.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)

              if annotation.title == "Center" {
                  let configuration2 = UIImage.SymbolConfiguration(pointSize: 20, weight: .thin, scale: .large)
                  let stdImage = UIImage(systemName: "star.circle", withConfiguration: configuration2)
                  let flippedImage = stdImage.withHorizontallyFlippedOrientation()
                  if parent.routeMeta.headingLeftToRight {
                      annotationView.image = stdImage
                  } else {
                      annotationView.image = flippedImage.withTintColor(.systemRed, renderingMode: .alwaysOriginal)
                  }
                }
              return annotationView
          }
