Billing info not present in data layer when logged in as guest

Hi there !
I am having issues with Google Ads conversions (not getting email address for enhanced conversion).

I realized that when the user is logged in, all the info comes along when the “purchase” event gets fired.

However, I did a test without signing in and I confirmed that very few values from the transaction are pushed to the datalayer. Is this behavior expected? See snippet belowe from the datalayer content. I am trying to use “customerBillingEmail” which comes empty when signed as guest.
