Enable custom permissions

Checklist custom permissions can be enabled on the Jira Settings > Apps > Permissions page under "Issue Checklist" header as presented below:

When enabled, users will be able to view or work on the checklist depending on permissions granted in project settings.

When first used, the required permissions are not granted so the checklist becomes read-only (if the first toggle is enabled) or not visible (if the second toggle is enabled).

In that case, you need to grant proper permissions to users as explained below

Configure custom permissions

Classic (company-managed) project

Navigate to Project Settings > Permissions to grant permission in a project:

Next-gen (team-managed) project

To grant permission in a project:

Navigate to Project Settings > Access
Click the "Manage roles" button in the top-right corner (Manage roles dialog will pop up)
Click the "Create role" button (Create role dialog will pop up)
Select the "App permissions" tab and next configure a new role (name it, select the permission, select users/groups who will be granted the permission)
