Great app but... I've read every message there is yet have a notification icon that says 109 unread. Can't clear that in anyway. Removed the app  installed again. Removed icon and replaced. Issue persists. Response 2: there's no reset badge counter reset option as advised. Response 3: Settings 》Applications 》Application Manager 》More 》Show System Apps 》BadgeProvider 》Force Stop  clear data and cache  disable any App Notifications then enable again. Restart phone. Problem resolved for S7 Edge :)
