Bricked after the auto 13.4 update I’ve got two HomePods and woke up the morning after the 13.4 update to only one working! I screenshot the settings (just in case), removed it from the home app and tried to readd it, but it was no longer visible. I then powered it off and tried a reset, but nothing, no light, no sound. Any ideas?

No Apple shops open so just wondering if others have seen similar?
