For the last few days I have been getting a voicemail update message in my notification bar. I click on it and it gives me the option to cancel or update. I hit update and it goes to the app but does nothing else. I have gone to the app and hit the settings and go to the check for updates option and try it there. Still nothing. I have not been able to update the app. I have cleared the notification bar but the update message returns every time I use WiFi or 3g or 4g. This has occurred multiple times. Any ideas on what is happening???
