My Moto Z has been accumulating unread SMS messages through the default Message app and it's driving me crazy. Every time I talk in a different conversation it adds another unread message to the notification counter even though there are no unread messages. It doesn't matter if it's a group text or to a single person, but each new conversation I enter does this. I've tried a hard reboot, force stopping the app, and clearing the cache but none of them have worked and I'm not really sure where to go from here, help would be appreciated. All my phone and all of the apps are up-to-date. Thanks.
