I make a lot of online purchases and have no difficulty tracking deliveries unless it is Royal Mail. I paste the tracking number in (no errors) and I always receive the message "Sorry, we're currently unable to confirm the status of your item with reference [xxx] . Please try again later." I keep trying on successive days, with no luck. I could understand this happening on occasion, when the system has not been updated, but not for every single Royal Mail delivery. I have no faith in this service at all. Hermes, FedEx and DHL are the other companies I am used to and I have been completely happy with their tracking services.
