When Trying to Send Documents from using the "Modern Experience" via a Workflow, files cannot be dragged and dropped into the field to attach it automatically. It looks like it was designed to, but all it does is open the file in a new page of my web browser (a sign that the webpage does not recognize I am trying to attach something.

So that means when I'm using a workflow (which is meant to save time) I then need to click the link that says to "attach a file" and then go digging through my computer (or the files on my companies network) to find the file that I need to send. Please fix this before getting rid of the classic experience (or better yet, don't remove the classic experience at all).
