Sharing notes not possible

@Christoph Busch  Are you able to share when clicking on the Notebook kebab menu and clicking "Share"?

Thanks for your help, Ali. The functionlity with the share-button or in the kebab menu/share is the same (see image). In both cases a sharing window opens with the possibility to share in puplic or with a group. Neither works. In both cases the document opens but without the content - just the document name like in my first image.
