- Login to a site the is using the Improved user management experience
- Navigate to Directory > Users
- Select Show details on the Organization admin
There should be an option to 'Edit Jira Properties' as there is for non-organization admins

The Organization admin has access to all products, so does not see the '...' next to Jira products that would allow 'Editing Jira properties'
