Devices on different AP's on same SSID

Question

I have Apple TV's and Macbooks on the same SSID. It appears when one of those devices roams to a differnet AP, I can no longer see the TV. However, when both devices are on the same AP, there is no issue. Not sure what to look at to try and resolve that? Any help would be appreciated. Running XG and APX 740's. Thank You

Hi Brent, are the VLAN settings same across the APs? After roaming if the destination AP does not have the same SSID-VLAN combo, then the mDNS packets which Apple uses for discovery will get dropped. For the discovery to happen, both the devices should be on the same backend VLAN.
