Hi,
Recently tracking from Correios is not working properly in the Deliveries app. It only updates the last event in the tracking, so if the object was already shipped it does not show anything until the time the tracking number was added to the app.
Since sometimes some "garbage" appears (movements that are not from the current tracking number), it needs to clear the tracking history and now the app have been unable to show all movements prior to that time, only the last one and those following it.
Please fix it ASAP.
