I bought the app because the demo version was promising. Now when I start the app is very often that I do not own this. It was only after I started the phone, it will work again. The purpose is about app and widget to save plenty of time and to control the box. But if I have to start every time the phone that is anything but time-saving. On the contrary, it is useless.
It may of course be that the app each time checks on Amazon. I do not care how the license will be checked, as long as it works. For other apps there are no problems.
