Upgraded!!! my Dropbox installation on my work M1 MacBook Pro to the File Provider version, the app had a Beta badge in the top left which was downloaded from the link on the DropBox website.
So far so good, the folder structure was replicated in the cloudstorage folder in the library, however there were no files or placeholders, even in subfolders.
Tried uninstalling and reinstalling Dropbox with no joy.
Finally signed out and signed in again, and then the old app and file structure is recreated, what a mess, I now have files all over the place.
Mac OS 13.4.1 Ventura
