Apple TV app on windows doesn't display family sharing at all

There's no way to see movies that have been purchased by someone in my family group.

Yes shared purchases is configured and works fine on the iOS apple TV app for both the primary and the family member's AppleID.

In the Windows Apple TV app if you search for a movie that you own through a shared family purchase it will let you watch it. So it is clear that the ability to watch movies purchased by the main family apple ID acc holder is working fine. However the Apple TV doesn't show shared family purchases anywhere.
