Environment
SaaS (https://sentry.io/)
Steps to Reproduce
- Configure an Alert with Critical, Warning, and Resolved thresholds
- Trigger the alert so that it passes through warning/critical states and quickly resolves
- 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
