iOS - MPVolumeView not showing Speaker and iPhone options always

Question

Currently I am working on an app, where I have to play some voicemail messages using Play button.So I have to employ MPVolumeView to let user to switch over different audio routes. Below is my code snippet how I am adding the view to my view controller:

 let volumeView = MPVolumeView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
    volumeView.showsVolumeSlider = false
    volumeView.tintColor = UIColor.gray
    
    for subview in volumeView.subviews {
        if let slider = subview as? UISlider {
            slider.isHidden = true
            slider.frame = CGRect.zero
            break
        }
    }
    
    if let airPlayButton = volumeView.subviews.first(where: { $0 is UIButton }) as? UIButton {
        //let customImage = UIImage(R.image.ic_airpods_bluetooth_dark)?.withRenderingMode(.alwaysTemplate)
        airPlayButton.setImage(R.image.ic_airpods_bluetooth_dark(), for: .normal)//airPlayButton.setImage(customImage, for: .normal)
        airPlayButton.frame = CGRect(x: 0, y: 0, width: 40, height: 40)

        _ = airPlayButton.imageView
           let symbolConfiguration = UIImage.SymbolConfiguration(pointSize: 40, weight: .regular)
           let sfSymbol = UIImage(systemName: "airplayvideo.circle.fill", withConfiguration: symbolConfiguration)
        
        airPlayButton.setImage(sfSymbol, for: .normal)
    }
    
    self.vwMV.addSubview(volumeView)

And here is how I am initiating the audio session:

 audioSession = AVAudioSession.sharedInstance()
    
    do {
        try audioSession?.setCategory(.playAndRecord, options: .allowBluetooth)
        try audioSession?.setActive(true)
        //try audioSession?.overrideOutputAudioPort(.none)
    } catch {
        print("Failed to set audio session category: \(error)")
    }
    
    NotificationCenter.default.addObserver(self, selector: #selector(routeChangeEventHandle), name: AVAudioSession.routeChangeNotification, object: nil)
  

Problem is, I am facing the 2 serious bugs with the above implementations:

1. I don't get Phones earpiece and Speaker options always
2. However, When I get both option, when I switch to Speaker options, the dialog shows me that as iPhone, after clicked. Please check the image below:
