Not working!!!

I downloaded this app and tried to open it for the first time, after signing in to my Facebook account and sharing the post on my Facebook page for their advertisements. The login in circle kept spinning until it stopped and said check your Internet connection and try again later. So trying again several times with still no connection. So I tried to re-download the app and did the whole process over again and still nothing. Why could this be happening ? Not a very good app have never been able to use it. Maybe if they fix this problem then it may be a very useful app.
