Hi, since the April 2018 release, it is not possible to sort A-Z on a chart axis, only Z-A. When clicking A-Z on the dropdown elipses, nothing happens. It is possible to sort by a measure but not A...
I should add that you can get to an A-Z ordered axis in my example eventually by continually clicking Sort by Category in the menu until it happens but there doesn't seem to be rhyme nor reason to it
