I wanted to update the pdfs which are delivered with various lead magnets, only to find out that I can't. I can't upload a new file. I can't even duplicate the old email. So when I created a new email and deleted the old one, people started emailing me that they were getting an error trying to access the old email. Which makes sense, but that's really lame and definitely wasn't an upfront thing explained, which may have slightly helped the now bigger mess I've managed to create just because I can't edit the file for an existing lead magnet.
