iOS App - Issues getting subscription state

I am working on implementing RevenueCat into my iOS App. I am able to make purchases using the sandbox environment and within the RC Sandbox Dashboard I am able to see that the Firebase Authentication id I am using is displaying properly as the RC Unique ID. 

To be clear, I am using the automatically generated Firebase Authentication Unique Identifier as the UID on RC. 

The issue I am having is determining the subscription state. Following along with the example project included in the swift package. I am attempting to determine state using the following code…

 

    @Published var customerInfo : CustomerInfo? {

        didSet {

            subscriptionActive = customerInfo?.entitlements[entitlementID]?.isActive == true

        }

    }
 

I have noticed that upon launch, I am unable to retrieve customerInfo however, when I logout then log back into my Firebase Auth account - it will display customerInfo? I am not sure where I am going wrong.
