descending sort broken

This is not an idea - it's a complaint. The option to switch the sort order on one field is no longer working. Example: I have a chart with Issue volumes over time and the default sort order for time is decreasing when I typically show time as increasing. I would normally click on the time field in the sort area on the chart to flip the order, however, now when i do that the chart decides for me to sort by issue volumes. This feels like a bug and I do not see a good place to report bugs. Please fix this asap as we cannot develop new charts based on time while this continues. Thanks Eugene Bing Ads Global Support
