CarPlay: CPNowPlayingTemplate doesn't show any information

Hi, I'm currently working on integrating CarPlay audio support for our existing news app. The goal is to choose an audio stream from a CPListTemplate, play the audio via AVPlayer and display the CPNowPlayingTemplate with the information I setup for MPNowPlayingInfoCenter.

My issue:

The CPNowPlayingTemplate is neither showing any kind of information nor does it respond to any button but the audio is playing as expected. Also the buttons don't reflect what I setup on MPRemoteCommandCenter.

I'm working on an iPhone 12 mini with iOS 16.0.2.

What I already checked:

• Entitlements-File includes com.apple.developer.carplay-audio and com.apple.developer.playable-content both set to true
• tried loading an artwork from URL as well as using a system icon
• tried to play different kinds of audio streams
• I'm calling beginReceivingRemoteControlEvents before AVPlayer starts playing the asset
• Same behavior with the new CarPlay Simulator and on a real audio device inside of a car

Here are some code snippets I'm using right now:

DispatchQueue.main.async { [weak self] in
            guard let self = self else { return }
            try? AVAudioSession.sharedInstance().setCategory(.playback)
            try? AVAudioSession.sharedInstance().setActive(true)
            UIApplication.shared.beginReceivingRemoteControlEvents()
            self.player.pause()
            let avAsset = AVAsset(url: asset.url)
            let item = AVPlayerItem(asset: avAsset)
            self.player = AVPlayer(playerItem: item)
            self.player.play()
        }

let artwork = MPMediaItemArtwork(boundsSize: image.size) { _ in
            return image
        }
        var nowPlayingInfo = [String: Any]()
        nowPlayingInfo = [
            MPMediaItemPropertyTitle: title,
            MPMediaItemPropertyArtist: artist,
            MPMediaItemPropertyArtwork: artwork

        ]
        DispatchQueue.main.async {
            MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo
        }

let commandCenter = MPRemoteCommandCenter.shared()
        commandCenter.playCommand.isEnabled = true
        commandCenter.pauseCommand.isEnabled = true
        commandCenter.seekForwardCommand.isEnabled = false
        commandCenter.seekBackwardCommand.isEnabled = false
        commandCenter.playCommand.addTarget { [weak self] _ in
            self?.player.play()
            return .success
        }
        commandCenter.pauseCommand.isEnabled = true
        commandCenter.pauseCommand.addTarget { [weak self] _ in
            self?.player.pause()
            return .success
        }
        let nowPlayingTemplate = CPNowPlayingTemplate.shared
        guard interfaceController?.topTemplate != nowPlayingTemplate else { return }
        if interfaceController?.templates.contains(nowPlayingTemplate) == true {
            interfaceController?.pop(to: nowPlayingTemplate, animated: animated)
        }
        interfaceController?.pushTemplate(nowPlayingTemplate, animated: animated)

Thanks in advance for any kind of help!
