The import is possible if you have less than 5 users. By default the worker group CRM
will have only one organization and will have 5 active users. So the organization that you are importing will be the only one available in the environment. If there are more than 5 active users, you might face challenges during the import process.
Had the same ? mark, its so clear now.....
