I get mail notifications for received shares i already canceled

Although i canceled a share received from a user on the same server, i get notifications, if he adds new files to the shared folder.

He shouldn’t be able to add files if you cancel a share??

Thank you for your reply.
The share has been made from his side.

Which versions of Nextcloud are you using? Try to update to the current version (10.0.1) and if the problem still exists, report it here: https://github.com/nextcloud/notifications/issues

Just got a notification email again. Seems like this is still an issue. I’m using version 10.0.1 (stable).

Then report it to the bugtracker and post a link here.
