You probably have jinxed the whole thing lol. I too would like to know the reasoning for the small rectangular shape bottom left of the screen. No interference yet this evening that i've noticed, and good news about the wider screen format, as this sometimes changes between adverts when viewing old shows.
I've been watching Gold the past week through the Black Roku box and Android Phone, and the problem definitely seems to be fixed....finally! This has taken many months! The little white box in the bottom left hand corner is a curious addition, but not annoying. I don't like that old shows like Only Fools don't broadcast a 4:3 signal anymore though. I have to keep manually changing the aspect ratio on my TV. At least when Gold was glitchy, the aspect ratio changed automatically to suit the format the programme was recorded in.
What about the white box bottom left hand corner?. when will this get resolved
that’s the Now tv watermark it’s on the right hand side on the sports channels so probably staying, although it seems a lot brighter than it is on the sports channels
