Initially after using the newest InDesign update for 2020, I tried using my old workspaces. But I found I could have only one document open and working at a time. I would have to open one document, work on it, save, and quit. Then I could open another and do the same thing. Obviously this is not productive, especially when you might need to copy something from one document to another. So, I have been using new and different of the stock workspaces to get me through in the hopes this will be fixed. Thanks.
