After deleting a voicemail message, I expect the message waiting light to stop blinking after a few seconds. Several times I have noticed that it may take a long time to stop. For example, tonight, it still going strong even though I deleted the only message about 2 hours ago. What gives? And yes, I know this is a first world problem.
The issue with the voicemail indicator (sometimes called the 'MWI', or Message Waiting Indicator) has been fixed as of yesterday (8/16) evening - please do contact support if the light is still stuck on.
