In the Network Watcher Service, I am seeing blank Topology for Selected RG and VNet. I am the Admin and Owner
@Madan-7627 If you have the required permissions, and you have enabled Network Watcher for the region that the VNET is in, your next step will be to check using a different browser, and try getting the JSON data via PowerShell or the CLI.
If you are still unable to get the topology, your next step will be a support request to troubleshoot further with Azure Support. If you do not have a support plan, please let me know.
