  1. Investigating

We’ve identified the technical trigger and are deploying a fix. We'll provide an update in 30 minutes or sooner if additional information becomes available.

  3. Resolved

    We've validated that the fix resolved the issue and child windows are now displaying content as expected. You may need to reload Slack using Command + Shift + R (Mac) or Ctrl + Shift + R (Windows/Linux) in order for this fix to be reflected on your end. We're sorry for the disruption this caused to your day.
