If I give someone access to an entity, and it have a to-many relationship to something else, the behaviour is inconsistent in compact view vs relation view. It will show “3 private entities” in compact view, and if they have editing rights, they are even able to unlink those private entities. But in relation view it will not show any entities and they can’t edit anything. I would prefer it to not show any entities if they do not have access to the target entity.
