Wireless clients iOS ( 11.0.1, 11.0.2 ), Android ( 7.0 ) can't see games hosted by other wireless clients.

A wired client ( android version running on linux ) can host games that can be seen/joined by wireless clients and can see/join games hosted by wireless clients.

wireless settings has AP isolation disabled ( see screenshot ).

Discovery of wireless games stopped working a few versions ago, we've been able to circumvent it by directly connecting by IP - but now you need a XBL account and allow full multiplayer to do this, so I would like the underlying bug fixed.
