Before you can start using the navigator editor you need to login to Content Glass social-account using your managed-app user/password credentials. 

1. Go to your webiste, where CG was installed.

2. Click Content Glass tab (or button) and on the main menu click "Login" button. The social-accounts view is open.

3. Click the "connect" button for Content Glass - Logic view is presented.

4. Set your username / password credentials. For managed-app admins the username is the same as store domain and the password is the same password you set once you reset the password (either on first time or after that). For example in the case of Shopify store running on domain: "giladtiram.myshopify.com"  the username is set to "giladtiram.myshopify.com".

5. Upon login refresh the page.
