I'm just curious at how many shows failed to sell out fully, and had to have the upper level behind the stage curtained off? These are the ones I know of;
San Jose 2
Chicago 2 (I saw it with my own eyes!)
Any others? I mostly blame the ridiculous prices, combined with the fact that U2 had just played large stadium shows in most of these markets in 2017. Also, let's be honest, declining general interest.
