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 ?
