Great series on the Spring 17 release Jen! One quick correction for you as it relates to Contacts to Multiple Accounts and Person Accounts…this is a Classic AND Lightning feature. I will also add that a related contact on a Person Account can be a business contact or another person account.

Thank you, Cari, for the heads up. I have moved the feature out from Classic only onto the Lightning and Classic page and included the additional tidbit about the related contact.
