We've seen this in editing with 2.4, we create a feature, with the symbology set to all features the same, i.e. a simple red line, we draw a new line, it is selected (highlighted), we deselect line and it simply disappears. The new feature is visible in the attribute table, it just, for some reason does not draw in ArcGIS Pro. If you hit the refresh it will then draw, it's like there's a lag in the refresh of the map somehow, very frustrating. Is there a graphics setting or something we can try to fix? Otherwise it's basically, create a feature>refresh button in lower right > create feature > refresh button....this is so lame.
