I read the thread titled "Create and enable a compact layout : Trailhead Challenge" and I thought that was my answer but I did the link to the Contact page correctly and I am still getting the error.  I have refreshed my developer version of Salesforce and I have refreshed my Salesforce1 app on my phone.  


The actual compact layout I built in the wizard but could not locate the place to set it as the default until I search by title and it was already set as default in teh Contact page.

Below is the screenshot from my phone showing the page layout is working properly.


Any suggestions?

I completed the challenge and also tested it using my iPhone and I am able to see the action and the layout per the challenge.
However, when I "check the challenge", it says incomplete because "Challenge not yet complete... here's what's wrong: 
The 'Update Account Information' publisher action was not added to the account layout".

There appears to be some issues with the checking process - someone please validate.
