I removed the link from the classic pages and then edited the lightning page to add the component but I still get this error - 

Challenge Not yet complete... here's what's wrong: 
Didn't find a replacement for the UpsellCrosssellOpportunity link that uses the CreateOppty custom Lightning component.

Why?

I am working on the Trailhead Superbadge: Lightning Experience Rollout Specialist: Step 4

This feels like a simple step but I can't figure out if I'm overthinking it or underthinking it. 

It sounds like it wants me to customize the highlights panel but that is controlled by the compact layout. And you can't currently assign compact layouts by profile. Which is what it wants me to do. Tip/Hint to get my out of my clouded mind that I'm in...? 

Challenge number 4 is described as:
As described in the requirements, customize Accounts so sales reps see a highlight of the details they care about most, while Paloma sees a highlight of the details she cares about.

important account details for sales reps are:
• The account’s name
• How many employees work at the account
• What phone number to use for calling the account
• Rating of how easy it is to do business with this account

Paloma’s priorities when working with accounts are:
• The account’s name
• The type of account
• What phone number to use for calling the account
• Parent account name, if any

Customize Accounts so sales reps see a highlight of the details they care about most, while Paloma sees a highlight of the details she cares about.

Attempted solution: I would achieve this by modifying the compact layout which in turn updates the highlight panel component on account record detail pages



Attempted solution 2: The two profiles that are created by setting up the org for this challenge are Custom: Sales Profile (for sales reps) and the user Paloma uses just Standard Platform User. I tried modifying their respective page layouts to isolate the fields they required into a new section as well as dragging them into the highlights section of page layout but it still yields an error.

Error on both solution attempts:

I'm struggling with the custom lightning component on this part. I don't have much background coding and am having trouble finding resources to help me achieve coding the lightning component. If someone could help give me some framework code to create a custom lightning component to hold a URL or direct me to a resource that help break this down I'd be very appreciative.
 

when you select setup cog there is no options for "All Setup" just setup, when checking App manager there is no lightning service?

Followed the trailhead procedure exactly but still can't get service setup!
