Send email when adding file in groupfolder (edit: email is also not send when adding file in regular shared folder)

Is it possible to configure activity in a way that it sends an e-mail to each user of the group, when a file is added into a groupfolder?

So far I have no success, although I checked the box “New file or folder has been created” of the activity settings…


I could observe the same behavior for regular shared folders.

User x creates a new folder and shares it with user y.
User y receives an email notification about this.

If user x adds a file in this newly shared folder, there is no further email notification for user y.
Is this intentional, although user y has checked the “new file” box of the activity app?

Edit: I opened an issue on github here:
