suspiciously, all three of my Nanoleaf devices went offline to Indigo at almost exactly the same time that I updated my phone to iOS 16.
All three (two sets of OG panels and a Canvas) responded to the iOS app. All three started responding to Indigo again once they were power cycled. None of them responded to my normal troubleshooting that I use prior to power cycling.
This is weird for several reasons. I'm used to ONE of these going non-responsive, and have some triggers set up to reconnect the panel via Unify to the network, or to restart the Nanoleaf plugin in Indigo, or both.
Can't recall ever seeing **all** panels going NO ACK at the same time before. And I did upgrade to iOS16 on my phone at almost exactly the time that Unifi reports them getting 0 connectivity.
Super weird.
