Root Cause
The advanced filters in the Kanban search bar were not working correctly due to a change in strategy. Initially, the feature was set for a small group of users, but a new setup enabled it for everyone, which might not have been the user's intention.
Resolution
The strategy was removed, and the feature was disabled for all users. After this, the issue was fixed, and the feature was gradually reintroduced.
Action Plan
To prevent similar issues, support will need prior approval before making changes. We will explore adding permission controls and separating operational features from product rollouts.
