  • Publication number: 20250111072
    Abstract: The described embodiments set forth techniques for managing digital media item delivery queues associated with a user and/or with a user device. The techniques provide a framework for establishing and subsequently modifying or limiting access to an allocation for digital media items managed via a digital media item delivery queue associated with a user and/or a user device. In some cases, a user and/or user device is allowed limited access to a digital media item delivery queue allocation, while a negative status for a previously provided digital media item is unresolved, based on a set of limited access criteria being satisfied. Exemplary limited access criteria include an account standing for a user of the user device or a type of digital media item request, e.g., a subscription renewal or modification to a current, ongoing subscription for the user device or a user thereof, and the like.
