BOX used to allow creation of BOX View apps before. There is no option to select BOX View API today. Did this change or is there a way to switch a Content App to a view app?
According to an email from Box Customer Services, they are no longer providing the View API for free users.
So if you are a free user, that is why you can no longer create a View application.
If you are a paid developer or trying to replace a View Application you are advised to contact Customer Services.
