Chrome cast did the 10% circle going to 100% when turned on so guess it was updating.
Now when I run Lightbox on my iphone6 I can't get the square with the wifi signal in right corner of phone.
I have turned phone on and off, deleted and reinstalled Lightbox on phone and still no success.
Yet Netflix and Youtube applics on Phone cast fine, so guessing not a network problem on my side.
On Spark fibre and just using Sparks DNS settings.
