Hi all, after yesterday's update on my iMac (Catalina 10.15.1), today i've downloaded some pdf and putted on desktop, as usually. I used to run an app call "Clean" that, at the end of the day, automatically clean the desktop by putting every kind of download in a document folder, divided into months. Obviously you can cancel the documents in the desktop manually as usual, but today, after the download, I can't. They don't move from the desktop. What did I do wrong? Please help.
