Hello NaviCoding
Azure Resource Manager sometimes caches configurations and data to improve performance. When you assign roles or remove role assignments, it can take up to 30 minutes or more for changes to take effect. If you are using the Azure portal, Azure PowerShell, or Azure CLI, you can force a refresh of your role assignment changes by signing out and signing in.
