They mention in their official website that it will not support android box, means that they didn't allow Unifi Play TV to play on TV. I have try using Airplay to push the video from my iPhone to Apple TV but they block it. It can only using mirror mode which it is not full screen on the TV.
it is their official stand that the app does not work on boxes.
so that they need not answer any question about boxes.
it is true the mirroring does not get u full screen.
above is exactly the same when it comes to astrogo app.
however, there are boxes can do both of them nicely.
this has something to do with the firmware of the box.
some can install direct from playstore, auto update too.
some need to sideload, update manually new versions.
some need work on the box itself to hide root, etc.
such issues have been discussed in other threads, incl this one:
