Screentime does not count audio playback from background in music app

Screentime does not work for audio apps

I discovered that Screentime has a flaw with music and audio apps.

After trying it as parental control to limit media consumption I realized that background audio does not count towards the screen time. It is the same for all services like Apple Music, Play Music and Spotify.

Especially for small children audio books represent a big amount of the media consumption.

The same issue have all third party parental control apps on iOS and Android, too. But I hoped this would be better for a native first-party implementation.

Are there any plans to extend Screentime to use with music and audio services in a later update?
