A user is asking... say they send a message/file to a group of users and discover an error in the file. Can they just replace the file and users can still use the same download link? Or must they send a new message with a new link to the new/revised file?
They must send a new message with a new link, with the fixed file. LF's messages are like sent emails, its similar approach, when email was sent it can't be also changed. (Except Shares there you can just re-upload the file and link to the Share is still same)
