Wow! Super infuriating to see this issue I'm having today with Storyline 360 was an issue 7 years ago. Nice videos out there saying you simply apply your formatting to each state (works fine), select Done editing states? click the item, Double-click format painter, and voila... nothing happens. I tried it about 10 times in a row, watched the videos again, tried again, and came here. It's still not functioning. It'll only take me about 10 minutes to manually apply the formatting to a dozen objects, but sure do wish it was functioning as advertised.
