Trouble using app – Epson Printer Finder Review

I'm not sure what's going on. Both my parents have used this app and said it worked. I am trying it and all I am getting is a white box covering everything and I cannot access anything on the app. I have tried re-downloading the app and restarting my phone multiple times. I would like to give this app more stars, if I can get it to work.
