The update frequency of the UI is not going to be able to keep up as the radio will switch back and forth between lowest rate for broadcast and multicast and the max rate for unicast traffic. If you have another MT unit sniff the channel traffic while streaming and you will see each frame with multicast traffic having a tx bitrate 6Mbit/s in the radio TAP header. (Edit: added 2x frames from an AX2 for referance)
Attached are client captures from right now (Expanded DST MAC obvs):
AX2 running 7.17.2 with client on vAP that has “Multicast enhance”=enabled, streaming TV content (ax2.png)
AC2 running 7.17.2 with client on vAP that has “Multicast Helper”=full, streaming TV content (ac2.png)
Perhaps there is some specific set of circumstances where the current release does translate, but i have not yet found any example (IGMP, ARP etc)
