Scroll Bars are not working in Store Answered Follow notsure November 27, 2018 16:21 You have a lot of content in this area. I barely use mouse wheel scroll, but I shouldn't have to. Tried dragging the black oddly rendered bar down and it does not move or indicate where in the page I am viewing.

To be fair, that one does eventually update. -1
