- identified Sep 22, 2026, 06:43 AM UTC
We have identified a regression where the "Results per page" user preference is being ignored on legacy BlackLine grids (e.g., Match Sets, Alerts, User Admin, and Legacy Import Status). Affected pages are defaulting to 15 results per page regardless of the user's saved preference. The fix for this issue has been successfully tested in lower environments and will be rolled out first to Sandbox, where customers will experience a brief period of unavailability during the estimated 10–15 minute deployment window.

BlackLine has deployed a fix for the Sandbox issue. You should be able to resume normal activities. We will continue to monitor the situation to ensure there are no additional issues. We will confirm when the service is fully operational.

BlackLine has confirmed that the service is fully operational and we apologize for any inconvenience this issue may have caused.
