2. Choose a Different Region Try selecting another region such as: West Europe East US North Europe West US 2
3. Check Machine Learning Services Availability Visit the Azure Products by Region page: https://azure.microsoft.com/en-us/global-infrastructure/services/ Search for Machine Learning and confirm that UK South is supported.
4. Contact Azure Admin (If in a Managed Subscription) If your organization enforces policies, reach out to the Azure administrator to request an exception.
5. Use Azure CLI to Verify Policy Enforcement
