Wondering if anyone has had issues with Sonos devices all dropping offline after a reboot? We have a rather large network and Sonos devices are on two switches in two separated racks connected over fiber. What's interesting is I get "Multicast Success" on the diagnostics page but all of my devices show up not registered. Wondering if I may still be having some kind of multicast/ network issues. Only major thing of note in my opinion is that our router/ primary managed switch are not in the same rack as our Cp4-R. Thanks!?
