The issue with me was it kept freezing so deleted to reinstall..to find app missing. Agreed that this is very poor on NowTV/Sky's part. Just managed to reinstall with the hack mentioned and auto sign in seems to have worked.. Let's see if it will play nice now.
What a pile of crap!!!!
My old white NOWTV box barely works.
And now the app is removed from Xbox 360???
Pushing me towards Netflix more and more.
Zero customer service / support and STILL no true 5.1 audio!!!
