Dropbox now shows up as a regular old folder in the new iOS 11 Files app. The latest update to the Dropbox iOS aa brings full integration with Files, making it work much more like it does on the Mac and PC. For instance, now you can drag a file from a Dropbox folder into an iCloud Drive folder, and it just works.
