Hi all,

On my network I use hAPac devices as accesspoints (not as router). The clients are almost all apple devices. (mac(book), iPhone, iPad).
I am running 6.44.75 beta to get (ac) connectivity to the newer devices. With both 6.44.75 beta and earlier versions I see on the iOS
(all of them !) devices weird behaviour using either the facebook or Instagram app. other stuff seems to go smoothly. Often images,
and more often comments/ reactions do not load in the app, while connected with either 2 or 5 GHz to the hAP ac. (this is a network
with v6 enabled, if i disable v6 same behaviour). Macbook(s) are ok, seems the iOS apps are doing something that the mikrotik does
not like in my setup.
When I connect to another AP on this segment, that happens to be an apple time capsule (in bridging mode), I do not see the described
behaviour, so I have some suspicion on the Mikrotik device(s) (multiple) and / or their settings. (I already use LongPreamble)

Any suggestions where to look / what to do ?

After posting the issue on reddit one user suggested to set the multicast-helper to “full”
( from default ) on the wireless interface(s). This seems to has solved the issue at least
for now. What exactly does this setting do in relation to the observed behaviour remains
to be investigated.

Any comments on this ?

Multicast helper listens to multicasts and is helpful with it.
