I can not get this tool to work consistently or reliably (this tool replaces the label tool on the drawing toolbar in ArcMap, it is for labeling in the map/data view, not on the layout). I have a graphics layer in my map and there are label properties set up for the layers. Sometimes it will work with one layer in the map but not others (even though they are from the same source with similar label properties), sometimes I can add a few labels and then it will stop working, sometimes it will not work at all. When it doesn't work it returns “unable to create element” error. I have read through the documentation and not found any reasons for why it wouldn't work consistently. Has anyone found any logic to explain when it will work or how to make it work reliably? Is this a BUG? I use this tool frequently (or at least did in ArcMap and have been trying to in Pro....) and its very frustrating! Any answers would be appreciated!
