Groupon App Issue?

When I try to use my Groupon app on my Blackberry Storm2 it tells me "No  network connection is available. Please turn on the mobile or wi-fi connections."


When I go to manage connections, they are on. I deleted the app and reinstalled. I have turned my connections on and off. I’ve pulled my battery to reboot.


It used to work with problems as recently as two weeks ago. My friend who also has a this phone on Verizon is having the same issue.


Anyone have any suggestions?
