Hi, I've upgraded our Apple TV 4K (2nd gen) for the newer Apple TV 4K (3rd gen) because the old one will move to a new (off-site) location.

The Apple TV is my only home hub and my only Thread border router. For a brief moment, there were two (I only disconnected the old one. I only removed it from Home later).

I've set up the new Apple TV with the iOS link, and I've opted for unified homescreen and therefore the new Apple TV was instantly set up the same way as the old one. Incredibly easy, fast and no-nonsense. 10/10 experience. HOWEVER.

Immediately I was greeted with issues in Apple Home. The iPad said "Home hub not responding", referring to the old one. New one didn't show up. Long story short I was able to resolve that by removing the old Apple TV (via the room tile) and a variety of reboots, so I'm committed to the swap now.

The second issue is a bit of a headscratcher- I've got a selection of Matter over Thread devices in my home (smart locks and various IKEA devices), that are all mentioning "no response".

I tried restarting them (eg. pull out the batteries), re-adding them, and I've allowed for over 90 minutes of wait-and-see to see if the network would rebuild, more reboots,...nothing.

Anybody else that has observed this behavior or anybody that has any tips or ideas for what I should try? Swapping a Home hub should be pretty straightforward no?

As a sidenote, I recently had issues adding new MoT devices with my iPhone. They would all just time-out during the initial handshake process.. Never figured it out, but the workaround has been to use the iPad.

P.S. I'm using Tailscale on all devices but that hasn't been an issue before AFAIK. I've tried disabling it today with no effect.

Thank you!!

EDIT:
Update: Thanks to help from Prestigious_Money361 I'm fixing the issue by (painstakingly) factory resetting all my Matter devices so they can be re-added (and reconfigured..). This is the only thing that seems to work. Luckily I'm still about 95% Zigbee device count wise,...yikes.
