This has been a on going problem for the last couple of years it’s a Now TV problem .use the online chat to complain and ask for some credit on your account.I don’t think Now Tv have any intention of fixing this.
I only subscribed to Sky Sports through Now TV a few weeks ago (I subscribe to the entertainment and sky Cinema packages without issue.
The constant blurring of the picture is very annoying and quite embarrassing as I have a friend visiting to watch too! (Part of my support bubble!)
I have too broadband speeds and no issues in any other networks or streaming services!
