I'm trying to remove an App Service plan from my Azure subscription, however, it fails with the error that a web app is still associated with it. The name of the web app in the error message does not exist in my subscription. I've deleted all resources associated with the plan, but I still cannot delete the plan itself.

How can I resolve this issue?

Hi,

 Check if you can delete the "Zombie" web App from powershell using the cmdlet remove-AzureWebsite Refer the below link.

 If you are still unable to delete the App Service Plan, then I would suggest you contact Support with a free Billing Support Ticket.
