Unfortunately, Mikrotik v4 and v5 do not support multicast transmission from an AP if any of the associated devices are using power save mode. In practice, iPhones and Android phones, for example, use power save mode to conserve battery life.
I sent a support request to Mikrotik and they are working on it.
It does seem strange to me that there is no option to enter a DTIM value. Even basic consumer devices often have this under their "advanced" section. It does seem like a simple thing to add. They just finished doing major work to add the multicast feature back into v5.15, so I'm really surprised DTIM config didn't get added at the same time.
Anyone from Mikrotik reading this care to give us your view on this feature? Is there some reason that you don't want the product to allow the DTIM interval to be changed?
