Mikrotiks big secret, interworking-profiles=enabled !!!
You can search the Internet to find anything over how set interworking-profiles=yes, nothing by Wiki, you only find posts interworking-profiles=disabled.
When you make the question how to setup this to the Mikrotik Developers they do not help with any answer ???
This is the same like the cold war times, only top secret, but why ??? 
I also found a secret parameter !
roswell-alien-backdoor=enabled
Not sure how it exactly works, but i’m on it.
noib - I just now also found some hidden settings which I just enabled - default is disabled:
wireless-perfect-connections=enabled
wireless-txpower+256watts=enabled
wireless-rxsensivity–256db=enabled
Interworking is for Hotspot 2.0
I can give you another secret function. MUM Agenda search:
