Hi I need help downloading some free widevine MPD contents from an korean kpop app called UNIVERSE. (It supports English)

LINK: https://play.google.com/store/apps/details?id=com.ncsoft.universeapp&hl=ko&gl=US

There are a lot of free videos in the app but I am stuck in extracting the videos in every methods I know.

First of all, in iOS it is encrypted via Fairplay which is known to be impossible to crack. Packet Sniffer shows me some certificate files but I believe it's useless.

On rooted Android, the app doesn't allow me to play any videos when rooted. Thus, turning on some packet sniffing tools such as fiddler prevents me from even logging in to the app. When I turn on the packet sniffing tool in the middle of playing a video, it returns a MPD link but it never returns a license_url or anything.

The url for the MPD Link is

If anyone knows how to extract contents or at least can provide me a different approach, it will be highly appreciated.
