Does anybody else have trouble with the "New voicemail" notifications constantly showing on their phone? After I listen to my voicemail messages and delete them, it still shows up as a "New voicemail" notification on the home screen and in the notifications on the phone. I have no more voicemail messages (not even saved ones) but the notification won't go away. I am on a Nexus 5 with Lollipop 5.1. Thanks.
