voice control in anything from Apple (apart from dictation on iOS) is also horrible in German. I recently tried setting up a voice controlled shopping list via Reminders - it’s a nightmare (worked perfectly well with Alexa until Amazon cut off the API access)

I only use the AppleTV because it lets me control my TV via the iOS remote that's quickly accessible via Control Center.

maybe releaseWhenClosed is set to true, and you are releasing additionally after the close?
