The links bring me to the 'Recently Added' instead of opening the actual chart. Can be pretty hard to find the chart of interest if one is looking through a thread that is a couple of days old.. 5/23/18
On a computer.. tried several browsers. Turns out that if I just click on the link I get to 'Recently Added'. If I right click and copy the link to a new sheet - voilá I am referred directly to the chart. :-? 5/23/18
