Unable to reset HomePod Mini
Since updating to IOS 15.3 on my iPhone 11 Pro my HomeKit has stopped working and has somehow been reset. I have lost all my accessories and scenes that I had set up.
I have been able to set up one Apple TV 4K has a hub but I am unable to set up any HomePod Minis. They don't appear when I try adding an accessory. I have tried resetting a HomePod Mini using a) a connection direct to Macbook Pro and I get this message -" The HomePod software update server could not be contacted. An unknown error occurred (-39)."
I have also tried resetting by powering off, then on again waiting for a while screen so that I can reset. White screen does not appear - it just connects and works OK - so unable to reset.
I just want to set up my HomeKit again. Any advice to help me is much appreciated.
