I cannot drag assets from the library onto the stage. It just refuses to drag. Dragging div elements doesn't work either. Is this a bug?
Can you post a screenshot of your project, showing the Stage and the library item you're trying to drag from library to Stage?
Re: dragging div elements, are you having problems changing the layer order in the Elements panel?
I opened adobe animate again today to make you a screenshot and I was surprised to see that it is now working. Tbh, I had given up all hope. What I was trying to drag was the background image in the Create tutorial. Before, it refused to drag onto the stage and I had tried for a good hour or more. Dragging div elements to change their order didn't work either.
Fortunately, they both work now and I did nothing new, not sure how to explain this because I think I had tried closing and opening the application.
