The parcel tracking feature is great, but having to select the courier can be difficult when there are multiple options
Recently for a DHL UK parcel I had to select 6 different version of DHL from the dropdown before getting the right one to pull the details though.
There is a universal parcel tracking website that offers an API,
https://parcelsapp.com/en/tracking
on that, you just enter the tracking number and it pulls through the courier, something similar to that would be great.
