"After adding a friend and when checking the leaders I have a problem. My friend's name has disappeared and I am the only one there. There is spinning icon in the middle of the screen (as if it is trying to connect to the internet - to which I am already connected). I have tried to uninstall and then reinstall, I have shut down my phone completely and then started it again but it remains the same. Of course this runs my battery down. Why is there a spinning icon that I can't stop? Why can't I see my friend? What should I do?"
