Groupfolders and sharing

When i have a groupfolder for a group and add members to that group the see the groupfolder.
That looks greet.

But when i have another customer and i want to share a folder that is in this groupfolder and give the customer write access than he cant write to it. Is this a correct behavior??

I can’t confirm this… I was able to share a folder inside a groupfolder via a link and I was able to uplaod new files to that folder via that shared link.

Yes via a link it works, but when you give a local user access that is not in the group??
