    The big issue with the @SlackHQ outage isn't that threads are broken, it's that my Slack client keeps making it seem like I have unread threaded messages and it's driving me ******' mad.

    1/2 @SlackHQ has issues today... discussion from a Slack team: X: I keep getting Threads bolded, but it only shows me a nine-day-old thread. Still working better than MS Teams on its best day! Y: Teams works so great on Linux that MS is killing the desktop app.

    @SlackHQ you've got to help me. I have nothing in my Threads view but it won't mark as read and so I have the red circle of doom staring at me all day long. It's across multiple devices and persists through shutdown!
