Can't install Spotify for Android TV on nVidia Shield TV

[Spirograf]

I'm not able to install the Spotify for Android TV app on my Shield TV, it doesn't appear when I search for it in Google Play. Other unofficial apps appear, but not the official from Spotify.

If I do a global search (from the Shield TV start screen), Spotify Music - for Android TV appears. If I select it, I'm brought to the Google Play page for the app, but there's no option to install the app. I'm also not able to install the app on the Shield if I try from a browser on a computer, it says that this device is not supported.

Is there a regional limitation on the app?
