When I receice a voicemail, I get a notification, but when I open the app to view/listen, I get the following message: "Unable to update. Please try again later." The voicemail(s) only appear after I power the phone off and on. I end up doing this several times a day.
The app worked fine when I bought my phone; and I haven't changed a thing or installed any apps.
I've spoken to Support by phone - they told me about powering the phone off and on, otherwise were no help.
