I've tried to locate a watch live option on All 4 but there doesn't seem to be anything there, although it is on my mobile. There was an answer from over 3 years ago to the same question but surely this has been sorted by now?
This is down to All4 itself, but from my understanding you should be able to cast the content to the box/stick.
That being said the ITV hub on my Samsung TV didn't have Live channels until recently. Perhaps with All4 becoming All4+ subscription option there might be scope for them to add Live channels to other devices.

Lots of All4 apps on various devices don’t offer live channels, though some do.
I think the idea was that these versions of the app went with, or at least played on, a TV with the live channels on, though of course this is not always the case.
But certainly, the All4 app on the NowTV stick seems to be NowTV-specific, as if you look at the Help, there are a lot of NowTV-specific entries there.
