Which service can be added to the customer over experience (COE) despite being retired?

The SmartHub service can still be added to the customer over experience (COE) despite being retired. This is significant because the SmartHub, which is designed to enhance connectivity and provide customers with management functionalities for their devices, retains value even after its retirement status. The COE framework allows for certain retired services to still be accessible for customers, ensuring ongoing utility and support.

In contrast, the other options, such as Gizmo Watch, Team Total Service, and What if widget, may not hold the same availability status due to either their operational changes or complete discontinuation in customer offerings. Thus, the ability to still add SmartHub showcases its lasting relevance and the flexibility of COE in accommodating legacy services for customers. This distinction is important for understanding customer support options and the adaptability of service management in a rapidly evolving tech landscape.
