Out of the blue, I see a voicemail notification I've never seen before and it won't clear. I use YouMail, so in the past I've gotten the YouMail icon when I've had a message. My voicemail still points to YouMail's number. Last night the default voicemail notification showed up (the one that looks like an infinity symbol, sort of). When I bring down the notification message, and click on it, it calls my phone number, and doesn't clear. There is NO clear prompt at the top right when this is up. When other notifications came up, and the clear prompt did show up, clicking on it did not clear the notification icon. I rebooted the phone--didn't delete it-- and now the message just shows it was left when the reboot was completed. Can anyone help me get rid of this icon?
