Has the iOS Controller app started to use broadcast instead of multicast?

I have a multi vlan network, and soon was happily working across VLAN, with multicast forwarding setup between the vlans.

Its now not playing ball - ive done some packet traces, and from what i can see, the sonos controller app is now sending a broadcast request to 255.255.255.255 on port 1900

Has this changed recently? My PC related (mac) app works fine still, but the iOS apps stopped working.

I have moved all the sonos devices back into the 'main' vlan, ie the same network that the controllers are in, and its all working again, but i wanted the vlan separation

Thanks
