Group Folder subfolder permission problem

Hello everyone,

I’m using group folder apps in my nextcloud 16.0.4 server.

I have a special folder in which, everybody has read access. I want to give some users write access to subfolders, but whatever i do, they are still read only access to subfolders. Is there a way to give users subfolders write permission, without giving write access to main folder ?

If a folder structure helps, my case is

Group Folder -> Everybody has read
Subfolder -> some users has read/write

but all i get is
Subfolder -> everybody has read
