Reset and disconnected old Apple TV still show in list of hubs and says it's not respongnding
I've upgraded to the latest Apple TV, so I reset my previous older one to factory settings and I've removed it from the Home App, and from the list of my devices in the iPhone settings->iCloud page.
Problem is that the iPhone Home app still says that the old Apple TV is "not responding", and it still shows up in the list of multiple home Hubs (I have another Apple TV and a few HomePods).
Where else am I supposed to remove the old Apple TV from ?
