Having bought N-Photo from Google Play for my Nexus 7 for the first time with a view to subscribing, there are a number of links within the digital version which are supposed to take you to videos which compliment the articles. Unfortunately the links do not work.
I am afraid that you will have to type in the bit.ly URL address manually into your web brower at present. This bit.ly takes you to a YouTube channel for all the videos for that issue, so you only need to type this once per issue. We are working with Google to try and get these links clickable, so hope to add this functionality at a later date.
