I'm using Dynamics 365 Ribbon Workbench, but for few of my custom entities, the subgrid ribbon is empty. Home and form ribbon can be changed, but not Subgrid. It just seem empty.
Anyone knows if I'm missing a configuration, either in Dynamics or Ribbon workbench?


We have exactly the same issue. In our RWB solution we had an entity that had a word "information" in it. In one of the CRM forum posts [link below], it was said that Scott D. [RWB Developer] stated that SubGrid buttons in RWB solution do tend to disappear [or rather move into the either Home or Form grid] if the entity name contains word "information" in it.
