I have added some channels to the "Favourites" folder. To access this folder I have to press TV and scroll down through the main channel categories (entertainment, sport, etc). Pressing the blue button, which says "Favourites", does nothing.
A couple of questions arise from this:

1. What is the blue "Favourites" button for?

2. Is there a way of accessing the "Favourites" folder without having to scroll through all the TV categories?

Any advice much appreciated.
