My app stopped working/giving me real time location status of packages. It updates delivery status AFTER package is delivered to house.

Doesn't appear to matter the carrier, (UPS, FedEx, USPS, etc). App does not have any status and acts like the tracking number doesn't exist. Even the option to track on carrier's website, doesn't work. Last I remember, after the package arrives, sometime afterwards the app will finally update and say "Delivered".
