App is not working

I tried to delete and reinstall the app several times. I stained in contact with the Boingo Support Center by email. But the app is not working. Im not able to search for hotspots. And the list is always empty. If I try to search manually the app says that Im not connected to the Internet, but I have WiFi at home, or LTE on the way. The support was not able to help me.
