I have a subgrid in my Service Activity (serviceappointment) entity. The subgrid doesn't have the usual + sign for Add New/Add Existing. I have to click the button on the top to create it.
Is there a way to get the + sign?
I've tried removing some/all the Display Rules and Enable Rules in Subgrid Ribbon Workbench but it still doesn't show.
