Hello, 

In Pega Decisioning Consultant Curse, in the subject SHOW ME HOW TO SELECT THE TARGET AUDIENCE USING A FILTER, it's said that "to access customer properties you use the 'Primary Dot property name' construct. The Primary keyword enables you to access all customer properties."

However, when I got to CHALLENGE ME ADDING A SWITCH COMPONENT TO A STRATEGY, it says to reference customer properties using Customer.PropertyName.

Why that difference?
