Spotifies simultaneous audio-out (Airplay and HDMI) on Apple TV 4K broken?

Hi,

justed wanted to start using Spotify on my Apple TV 4K by sending audio out via HDMI and Airplay.

While this does work with other Apps on the ATV, it seems that Spotify is broken in that regard.

I tried it with both options we got:

a) running Spotify on ATV and using the Remote to group both outputs inside the „Home-Settings“ (pressing and holding the Home-button for three seconds)

b) using the Home-App on iOS and group it there

The settings do show the successful grouping of both audio outputs, but sound stops working on the HDMI-out while the airplay device receives the audio stream.

Is that a bug of the Spotify App on the ATV?
