Group Folder Permissions - inherit ACLs to subfolders and files

Nextcloud 16 enables granular file and folder permissions using ACLs.

I am having trouble when it comes to inherited (inheriting) ACLs.

What I want to achieve: Create a Group folder with no sharing permission at all.
Then I want to create subfolders and set granular permissions which are then inheriting to their children.

I’ve tried several permission settings but currently they’re not inherting to child-items and folders, even when I set them to inherit. - Or at least the child items do not show the previously inherited permissions.

May not help however beware of GF 4.1.3 trouble with advanced permissons #635
