Recently I asked a question that was similar (Parent node needs to display the scheduled date that is referenced in the child node), but requirements have changed and now I'm dealing with the Node A (parent) -> Node B (child) -> Node C (grand-child). Bear with me as I explain this.
Node A is the main parent. It contains an entity reference field that calls Node B. I've successfully created the contextual filter and relationship to display the necessary information from both Node A and Node B. Entering the mix is Node C. Node C contains one piece of info that needs to be displayed. There is an entity reference field in Node B that calls Node C.
I currently have a contextual filter and relationship on the Node B entity reference field, but the field from Node C isn't displaying. I'm sure this has to do with there being 3 layers to this view. Is there something here that I'm missing, or is views unable to handle the 3 layer relationship?
