Not an a issue on playback for me with now stick & Panasonic tv. Here are my images.
normal playback - perfect. Used constant colour to make sure.
paused - the blocking at the bottom but no big issue for me
the blocky screen when I rewind/fast forward, but it only appears for a short time
Folks I've got this exact issue and I am using an Amazon 4k Firestick. My bandwidth is always good and I have no issues with other football apps like BT or Premier. Has anyone ever found a resolution for this issue? It's driving me wild. I pay a lot of money for this privelidge and it's absolutely terrible quality because of this camouflage overlay.
There are a few threads on the Community about picture noise artefacts when watching Sky Sports over the last 24 months such has the camouflage effect, fog or mist or marco blocking noise on the background where i have inputted on a few of them myself.
I believe they are all related and just a different description on what the customer sees when watching Sky Sports with NOW.
Unfortunately i don't know the answer, where NOW will blame your internet connection which is not the case.
