Conference Management App - Create a Lightning Component with Server-Side Apex Controller:

Step 5: Add Component to the Speaker Record Page
Click App Default and then Assign as App Default.
Select the Conference app, then click Next and then Save.
Question: Does anyone know why Conference Management App is not listed for selection?


I am also getting this error when I verify the hands on challenge:Note all APEX codes saved without errors. and all other steps worked.
Step not yet complete... here's what's wrong:
There was an unexpected error in your org which is preventing this assessment check from completing: System.QueryException: List has no rows for assignment to SObject

Thanks in advance for your help.

I am trying to complete what I would think would be an easy task.. creating a new view.  However, I am on the Transaction Security page but I see no place to create a new view.  Also, I do not have the one page to create a new poicy.. .I have a wizard/lightning looking process.  Any help would be greatly appreciated!  Thanks!!  Fred
