[quote='870053022, DTS Engineer, /thread/810454?answerId=870053022#870053022'] K-MTG- what router are you using and, in particular, is it Ubiquiti hardware as well? [/quote] Yup, I'm using a UDM Pro. I have their switches and APs as well. I'm currently offsite from the home having issues so I won't be able to get the sysdiagnose from the Apple TV until next week. Currently, I just provided the sysdiagnose from my iPhone.

Yup, the bug ticket is FB21366014. Btw...I also see a few posts on reddit (r/HomeKit) regarding this issue.
