Yes seems positive so far, you’d hope bugs will be promptly fixed from this. Issue will be suggestions as it will be a few individuals suggesting changes that differ from the NowTV blueprint as it were.
I known Apple have human interface guidelines for iOS / macOS, would imagine they do for tvOS. You’d hope like many other U.K. providers they’d follow the normal layout. Saying that Netflix doesn’t and that works very well, Amazon not so much!
Same here re (lack of support for) Boost, got reply saying raised with dev team. Mainly I miss the enhancement to 5.1 sound. Not so much PQ as tv seems to upscale it very well, but obvs no sport at present where 50fps counts.
