I've tried restarting my Galaxy Watch, turning it off for the night, and checked my voicemail from the watch, but the New Voicemail notification won't go away. It's not a huge deal, just a little annoying.
Any suggestions? It happened before and fixed itself, but it doesn't look like it's going to this time.
I have the same issue, used my watch to listen to a voicemail for the first time, and now the notification keeps popping up saying I have new voicemail even though the mailbox is empty.
