So, in this trailhead unit, Customize Record Highlight with Compact Layouts, within the Lightning Experience Customization module, it has an odd tip at the bottom about having different highlights panels per profile: https://trailhead.salesforce.com/modules/lex_customization/units/lex_customization_compact_layouts

The steps in the text are:
1. Create a record type.
2. Assign the new record type to the profiles that should see a different highlight
2. Create a different custom layout, with the fields for the different highlight
3. Modify the compact layout assignment and assign the new one to the new record type

Then it says viola! it should work.  But it doesn't seem to work for me.  Everyone always sees the default.

Has anyone been able to get it to work?  Am I missing a something?
