Home Hub disconnection after iOS 18.01 update on Apple TV 4K

I set up a Home network with cameras using a new Apple TV 4K as the home hub. The my home set up was put on our main home while we went to Southern California for the holidays. When Apple up graded the IOS to 18.01 my wife lost her connection to the Hub on her iPad. When they they went to 18.0.1 she lost connection on her iPhone. At 18.1 I lost connection to the hub. (Message is there is no Home Hub). I was told by Apple that 18.2 would fix that. We are now at 18.2 and my Hub says it is at 18.2 but still I am being told that the Home Hub is not responding. I am still about 1,000 miles away from home and this wonderful Apple app doesn’t work. When I called Apple support I was basically told to go back home and call them on the phone. For someone that is always traveling, this is not acceptable. Either I need to find a resolution or scrap Apple. Oh my google nest camera that is about 3 years old is still working.

Any ideas?
