Hugs For Kids review for Open SignIn ‑ Social Login

I feel as if I must have installed a different app to everyone else here. The glowing reviews about the service sold it to me, and so I spent my time installing and customising the app. It looked great! Except on any mobile device as I couldn't get it to be responsive to different screen sizes. I figured I was doing something wrong, so I emailed. Three days later - no response. So I emailed again. Today is another three days later and still no response. I couldn't click 'Remove App' fast enough.
