Resolved

The issue users experienced with stuck Activity badges has been resolved. If users are experiencing any trouble, they may consider hard-refreshing their app using Command + Shift + R (Mac) or Ctrl + Shift + R (Windows/Linux) in order for this fix to be reflected on your end.

Again, we’re sorry for any inconvenience this issue may have caused you.

Cause Identified

We’ve identified the cause and are working on a forward fix. In the meantime, users may now try hard-refreshing their Slack app (Cmd/Ctrl + Shift + R) as a workaround to the stuck Activity badge. We’ll be back with another update once we have news to share. Thanks for your patience.
