I've done a few restarts but no change in behavior.
Here are some details and I've added a screenshot. Please let me know if I can provide anything else.
Android Headunit: Atoto S8 Pro
Spotify version: 220.127.116.112
Launcher is Launcher3
Here you can see how the Home link is behind the 'Back' button. I know Atoto customized the UI but even with a different launcher (FCC Launcher) I see the same. All other apps respect the status bar as far as I've seen.
