What are some common troubleshooting steps if the Azure DDoS Protection icon is missing when it should be present?

If the icon is missing, first, verify that the resource (e.g., virtual network, public IP) is actually associated with a DDoS Protection plan. Double-check the resource's configuration in the Azure portal. Ensure the resource is in the same region as the DDoS Protection plan. If the problem persists, check Azure Service Health for any known issues affecting DDoS Protection. Finally, ensure you have the necessary permissions to view and manage DDoS Protection settings.
