Environment

SaaS (https://sentry.io/)

Steps to Reproduce

  1. Configure an Alert with Critical, Warning, and Resolved thresholds
  2. Trigger the alert so that it passes through warning/critical states and quickly resolves
  3. Observe the order of notifications delivered to the Slack channel and thread

Expected Result

  • The initial alert state (e.g., Warning or Critical) should post first as the main channel notification or top-level message.
  • Subsequent state transitions (e.g., transitions between Critical/Warning and the final "Resolved" status) should follow chronologically as replies within the thread

Actual Result

  • Resolved state triggers the Alert notification in Slack first. Then, Warning and Critical states appear inside the Resolved thread
