5. postmortem Apr 29, 2026, 03:48 PM UTC

   Between 22:40 UTC on April 21 and 19:21 UTC on April 22, the Workspace Panel was not rendering consistently for users. Regardless of whether they had toggled it on or off, the panel did not appear. The issue was particularly present for non-Enterprise users \(Business and Pro accounts\). The impact was limited to the panel and did not affect any other UI flows within the Smartsheet app. The incident was resolved by rolling back the affected Workspace Panel to a previous known good version.
