I have just deleted/disallowed, the console app and the app I'm currently writing.
For the console the access token I was using before deleting the app carried on working, and when I got a new token, it didn't show the dialog, only opened the blank window before shortly closing it; I was not asked to reject or accept.
For the app I'm developing I don't hold the access token, but it got a new access token without showing the dialog; again I was not asked to accept or reject the app.
I have waited on both apps, still they carry on working, when they should show the Auth dialog.
Refreshing the apps list still shows I have deleted the app.
