I created a WAF back in May and have been successfully working with it until today, I went to save a change and got "There is already a site with this URL in your subscription" . I believe another coworker was trying to work with the WAS and added app with same name. We deleted that app however when deleting it asks you if you want to delete in a few other places (AV, VM ?) and I said no. Still have the issue with the WAF.
I'm just looking for an easy way to remove the duplicate offending URL from somewhere in my subscription so that I can continue to work with the WAF app and save a change to it.
