I noticed for every failed attempt when I wanted to create a new project, the appcelerator website has an instance of that app.
When I clicked the X icon to deactivate the app, it returned "there seems to be a problem".
Anyone can advice how to remove those unwanted apps?
As strange as it might sound, you cannot delete apps from the My Apps section on the website.
Maybe we should raise a ticket about that. I mean why would I want to have every project that I am working on(even if it is a test project) submitted somewhere and not having the possibility to delete it?
