Thread OTBRs renamed network, now all devices offile

[jvmahon]

The problem

I was using Matter over Thread devices on a thread network that consisted of 3 Apple TVs. All was fine.

I recently added an Apple Homepod which caused the Apple thread network to reconfigure itself and, in the process, it changed the thread network name.

Now, all my thread devices are offline. Is there any way to get them back?

I thought thread networks were supposed to be able to reconfigure themselves (even, at times, splitting into separate sub-networks and rejoining) and maintain connectivity. Any idea what went wrong?
