A user can delete a view which is created only by the user (Private view) while an admin can delete a view which is created only by admin (Protected and Public views).
If a default view is deleted, then the next default view in the following order of precedence is displayed:
- User view = Private
- Admin views = Profile, Role, User, Public
If a user does not set the default view, then the first view that is associated with the user profile is displayed as default.
