BonJour not working WLC5508, I tried other forums instructions

Question

Hi All, I have the attached diagram and I followed the instructions from another posts / forum cases and the Apple TV is still not working.
My questions are:
1.-The WLC controller and AP must be in the same subnet?. This is not my case, the AP 3500 is operating in a remote location and I have a centralized WLC 5508.
2.- I already configured the Controller --- > General --- > Broadcast forwarding (enable) + AP Multicast Mode (Multicast / IP: 239.20.226.197).
3.-I already configured the Controller --- > Multicast ---- > Enable Global Multicast Mode (selected) + Enable IGMP Snooping (selected) + Enable MLD Snooping (selected). Please see the attachment.
4.-Do I have to configure something in the Mobility Management --- > Multicast Messaging --- > (Enable Multicast Messaging + Local Group Multicast IP Address) ?????
The  Apple TV Device and Ipad are authenticated in the ISE using certificates with no issues and both got IP's from the DHCP for the WLAN Vlan assigned to the SSID activated (see pictures attached).
thanks in advance for any orientation,
Abraham

#When both appletv and ipad on wireless on same ssid and vlan then Multicast to Unicast works perfectly without any wired side configuration. Because the packet never leaves the wlc/hits the wired interface. To conserve RF bandwidth, if you prefer to use Multicast to Multicast for this scenario make sure to have Multicast routing enabled on wired side for all involved vlan interfaces from WLC. With M-U, wireless Multicast source and destination should be on same vlan for bonjour however AP and WLC can be on different vlan. Since the Multicast source and destination of the actual traffic belong to same vlan and it is also encapsulated on unicast capwap it will forward the packet without an issue, basically it dumps the Multicast traffic on same vlan.
#With the above scenario if you prefer to use Multicast to Multicast then keep the WLC Management, AP and Wireless client on WLC's management vlan. this way it doesn't require Multicast routing on wired side. So here, if AP is on different vlan than management then the intermediate wired device need to know how to dump the Multicast packet that is sourced from Management of wlc to AP's Multicast group address that's why we need the Multicast routing for WLC and AP vlan on wired side.
#AP Multicast - Multicast is required When we've wired apple device on same vlan like wireless then need to enable Multicast routing on wired side E2E for all the WLC involved vlan interfaces i.e, wired(wireless) client, AP, WLC management VLAN.
#Difference is, as WLC receives the actual multicast data packet, when using M-U it sends out the actual Multicast data packet encapsulated in unicast capwap to AP's ip (sourced from WLC's management interface ip) and with M-M enabled, it sends the actual Multicast data packet encapsulated in unicast capwap but send to Multicast AP group ip (sourced from Management ip of wlc) that is configured. It is applicable only for Downlink traffic ie., WLC to AP, the uplink is always unicast from wireless client to ap to wlc.
