I’ve read some of the reviews I don’t think it’s fair to blame a free tracking app but it’s more likely the seller is a scammer, why because I tracked my parcel from China with several apps and they all said the same thing, you’re package has arrived at the destination Country Sorting Facility, I asked what to do next to locate my package and was told to contact Canada Post which I have done, so in that case all the apps must be in on the scam together? doubtful, thanks for the advice.James
