Good point. I looked last night on my NowTV box (Roku) my Amazon Prime stick and on my Sony Android TV's Play store app with no britbox apps on either. I don't really want to watch it on my PC connected to my TV as the screen settings on my TV are for PC only and are to bright etc.So what platforms can you access this on? There didn't appear to be a Roku channel when I looked last night.
The website is particularly sparse on details and just shows Samsung, Apple TV, iPhone and Android. It also looks like you can stream on browsers as well.
