I've got the same problem. This has been going on far too long, as the first reports on the Virgin Forums date back over 2 years ago. If you can't have a working app then it shouldn't be on the App Store. I've emailed Apple to let them know but hopefully you can resolve this problem once any for all !!! I'd like to stay with Virgin and will wait a short while longer but will leave if this app isn't fixed. Many thanks
