Okay so I tested again just to check, and it still does not work . It seems like another user is having the same issue which makes me think the link is broken. The apk downloads but when you go to install it doesn't finish installing.  I'm not sure maybe it's a version issue? It says 2.6 but when you go to Download it's 2.4 so I thought maybe it could be that as well. I just wanted to give you a heads up.
