HomePod IOS 16.4...HomePod says it's not on same network
Ever since upgrading all my HomePod's to 16.4 and My AppleTV's to 16.5 I'm getting the error that Timers are unavailable as the HomePod is not on the same network as all my IOS devices. They aren't I only have 1 network in my home. Now I my have 2.4g and 5g bands with the same SID but this has never been an issue in the past. My Home WIFI AP is an XFINITY cable Router and AP.
Any ideas? I've rebooted everything multiple times but nothing seems to help.
