Mike Piontek, the developer of Deliveries, said that the app is losing function because shipping companies are not willing to provide the shipping data that the app needs to work.

In a post penned earlier this week, Piontek said that Deliveries is no longer able to maintain the same service that it used to provide because it relies on shipping companies and the app is not able to work the way that customers expect.

The Deliveries app will likely stop showing direct tracking information in the future. Delivery date, map route, and other details will not be available. To see tracking information, customers will need to use the "view online" button on the shipping company's website.

The Deliveries team will try to make the app as useful as possible for those who still use it, even though it will become less useful to users.

Over the course of the last few months, Amazon deliveries have stopped working, but Deliveries seems to be able to show shipping information from major U.S. shipping companies.

Delivery companies used to be able to track Amazon shipments from an order link, but that is no longer possible. It requires logging in to Amazon with a login and password, which makes it difficult to track. The app stopped working with FedEx tracking numbers, and there are also complaints about shipments not being able to be tracked.

When these changes were made by shipping companies, Deliveries may no longer be worth the $4.99 per year subscription price.
