No settings in "Andmin-Sharing-Email notifications"

Hello,
i faced with strange problem: absent of some settings in Admin-Sharing topic.
where are no few settings like

  • Allow users to send mail notification for shared files
  • Allow users to send mail notification for shared files to there users

I found it in docs https://docs.nextcloud.com/server/11/admin_manual/configuration_files/file_sharing_configuration.html

but I don’t have these options - see attachment

Email app exists, I got notifications only in case of “Activity”.
I faced with the problem during investigation of email notification in case of sharing something…

thank you a lot.
Alex.

Hello,
I’ve got the same behaviour on our nextcloud instance after upgrade from 10.0.3 to 11.0.2
Beside that, when users share a public link, there is no text zone for typing mail address.
Does anyone find a solution or a work around?
