Hi @robert_wing, by default Tealium does not leverage session storage, but our Data Layer Enrichment service for AudienceStream does, as well a page performance feature that we have leverage local storage. Both are required opt-in features.
I invite any user to state specific examples.
b.userType = sessionStorage.getItem('userType');
Then it would just be a matter of including userType as a variable in your data layer and you are good to go.
