I remember the flavor ban and thought to myself that it was going to be good to do so that it would not be as attractive to kids. The article is implying that the flavor ban did not stop kids from vaping. In fact, the ban corresponded with a slight increase in kids vaping, which does not make sense to me.

Of course, correlation does not mean causation and the two facts may not be directly related. Maybe kids heard all the talk of the ban and that served as advertising to get them to start. More studies are needed.
