# Troubleshooting Reviewer Access Issues

> This guide helps you resolve situations where users have read-only (reviewer) access to the Nextedy GANTT widget instead of full edit access.

export const LastReviewed = ({date}) => {
  if (!date) return null;
  const formatted = new Date(`${date}T00:00:00Z`).toLocaleDateString("en-US", {
    year: "numeric",
    month: "long",
    day: "numeric",
    timeZone: "UTC"
  });
  return <p className="mt-10 text-sm text-gray-400 dark:text-zinc-500 not-prose">
      Last reviewed on {formatted}
    </p>;
};

## Symptom

Users see the Gantt chart but cannot edit items -- dragging, resizing, and the Edit button are disabled. The Gantt displays a reviewer-level interface without editing controls.

<Steps>
  <Step title="Verify the User Group Configuration">
    The Gantt determines edit access based on membership in a specific Polarion user group.

    1. Navigate to **Global Administration > User Management > Users**
    2. Verify that a group called `nextedy_gantt_users` exists
    3. Add all users who need edit access to this group

    | Group                        | Access Level  | Capabilities                                        |
    | ---------------------------- | ------------- | --------------------------------------------------- |
    | `nextedy_gantt_users` member | Full edit     | Drag tasks, resize bars, create items, save changes |
    | Not in group                 | Reviewer only | View-only access, no editing                        |

    <Warning title="Group membership determines edit access">
      Even if a user has full Polarion project permissions, they need to be in the `nextedy_gantt_users` group to edit items in the Gantt widget. This is a Gantt-specific permission layer separate from Polarion's standard role-based access.
    </Warning>
  </Step>

  <Step title="Reload Licenses">
    After updating the user group, you must reload the Gantt licenses for the changes to take effect:

    1. Navigate to the **Gantt - License** page in Polarion administration
    2. The page automatically reloads all active licenses and applies the updated user access rights
    3. Ask affected users to refresh their browser page

    <Tip title="License reload is required after group changes">
      Simply adding users to the `nextedy_gantt_users` group is not enough. You must visit the license page to trigger a license reload. Without this step, the permission change will not be applied.
    </Tip>
  </Step>

  <Step title="Verify User Access">
    Ask the affected user to:

    1. Refresh the Gantt page in their browser
    2. Check that the Edit button appears in the toolbar
    3. Click Edit and verify that task bars become draggable
  </Step>
</Steps>

## Verify

After completing these steps, you should now see the Edit button in the Gantt toolbar. Clicking it should enable full editing mode, allowing you to drag task bars, resize durations, create dependency links, and save changes.
