This one seems unobtainable as far as I can tell (or maybe just glitched for me as I think others may have it).
Most apps such as this have a connection process that requires you to log in to your provider. This one does as well, however, I did that (had to in order to use the app, in fact) and did not get the achievement.
Additionally, some such apps have a secondary thing you can do. Select a settings option from the menu (usually a little gear icon) and select "Log in to your provider". This app does not seem to have that option at all and I believe that is why you cannot get this achievement.
11/28/2015: Over the holiday weekend they seem to have fixed the glitch issue and this is now achievable quite easily. Simply run the app, click the guide button and "Log into cable provider".
