One of our companie's websites has mistakenly be created as a web app (under MarketingHub's Web Assistant menu). I've tried deleting it and creating a website with the same domain, but the app will only allow me to restore the web app and not create something new.
First, can I make this change and if so, how?

Second, what exactly distinguishes a website from a web app? is a web app simply a site that runs javascript or is there more to the distinction?
