Phantom voicemails
My iphone 13 mini keeps sending me notifications that I have new voicemails. Additionally, there is a little red 3 by the icon for the phone app. Yet when I ring Voicemail I'm told there are no new messages.
It has been like this for several weeks now. I've tried turning off notifications, turning off the phone, then starting up again, but nothing gets rid of the phantom 3 calls.
Does anyone know the solution to this problem?
iPhone 13 mini, iOS 15
