I downloaded the app and paid for a subscription and the app never blocked a single thing! And time I tried to help any help or support it led me to the website and then would just circle me around from signing in to the advertisement page even though I had just signed in and had a subscription. I then emailed support 3 times through the contact link at the bottom of the website and still am getting charged ever month for a service that I do not receive and have been trying to cancel for 3months!!!
