I just noticed YouMail is no longer working. Even when I open the YouMail app and refresh it, it doesn't display the voicemails I have. If I call the VM phone number, then I can access the voicemails, but I get nothing from YouMail. I even tried the option of having YouMail call me (for me to decline the call) and leave a voicemail, but I didn't get a call.

I haven't made any major changes to the phone in awhile, so I don't think I did anything to cause this. Any ideas?
