We upgraded to 2020 yesterday and the first thing I noticed is that I have to click 3 times to place a dimension or 2 if it's a line and the dimension will not appear until you do the final click (instead of the old drag and drop). While using ordinate dimensions you have to click off  the detail for it to place (each instance) instead of just clicking a series of holes. I realize many probably haven't upgraded to 2020 yet but if you have and have some insight I'd appreciate it. I can't find anything in settings .
