I found other forum discussions about how to update from Legacy Paper to the "2020 release"... so that we can have our files all organized in Dropbox (storage)... versus the Paper file system.
Those discussions suggest that there was not a way to manually upgrade... BUT, since those discussions are 3 or 4 years old... I figure there must now be a way to do it... Right? There is a way to upgrade now, right? (Insert "Anakin / Padme meme here)
