Show or Hide Related Lists in ARC
Now related lists are hidden by default to give your users some
space. They can use the new Show Related Lists toggle when they want to see group relationships
and related list relationships all in one view.
Where: This change applies to Lightning Experience in Professional, Enterprise, and Unlimited editions where Financial Services Cloud is enabled.
Why: Related lists in ARC let users see the big picture, but all of those extra cards can be overwhelming when they’re not necessary. Hiding related lists by default gives your users a more streamlined experience, plus faster loading times.
