I have had an odd problem where the Android Messages app had a notification bubble with a number of 1 or higher. That is, the app acts as if there is one unread message. Looks kinda like this:
But when I check inside the sms messages app, I see no unread messages, no unsent messages, no drafts. There shouldn't be a notification bubble. The app acts as if there's a hidden message always there.
How can I get rid of this number?
