One core feature of the file manager (mac finder, windows explorer) addons of Dropbox or Google Drive is that person A can share a file with person B. Both can then edit the file in their file manager and changes are synchronized to the other person.
In my tests this feature does not seem to exist in my cloud desktop. I can only download files shared with me in the web client. I can add files into a share someone else shared with me, but I cannot change a specific file someone else shared with me.
Are my observation correct or do I miss something?
