Thanks for the clarification. We tested using the OpenAI Organization ID as you suggested. The MDM profile installs successfully and the device shows "Allowed External Intelligence Workspaces added" under Restrictions. However, when attempting to log in to ChatGPT with an account that belongs to the specified Organization ID, we still receive the error message: "Login failed: Please try with an account and workspace allowed by your administrator." It seems that even valid accounts from the specified Organization cannot log in. Could you confirm if there are any additional requirements, limitations, or known issues related to this? Thank you again for your assistance.
