HomePod connection issues with OS 16.6
I updated 2 x OG HomePods and 2 x HomePod minis to 16.6 recently. None would reconnect to WiFi after the update and the only way I could re-enable them was to remove each from the Home app, reset the HomePods and set up again as new devices. However after a little less than 24 hours they all dropped out again. Repeated the removal, reset, re-add and a further 24 hours later they all dropped out again.
I used to see them re-authenticating on my WiFi on an hourly basis before 16.6 - now only show up when I re-add them.
No changes to my home network during this period and no other devices are having connection issues.
Anybody else seeing anything similar? Has something changed in the network requirements with OS 16.6?
