My package said it was returned but I'm not sure why, I did input the wrong postal code on accident but I'm not sure if it ever arrived in Canada.

Hi, what happened with my package RV434041481CN? It has been 84 days and although it has been reaching Canada, it's still never been registered on CanadaPost so there is no way for me to ask CanadaPost regarding whereabouts and what happened to my package since it's not registered on their system and it doesn't come up on its website at all. I have been noticing that every packages from abroad especially from China that arrived in Vancouver has never showed any more information than just "arrived at Vancouver" and it's never even registered on CanadaPost too, there is no more information anymore afterwards. Exactly same thing happened with other package RE071594545CN for example. Please explain. Thx

My track number is: LT677611291NL
I wonder what happened to my package? Nothing has happened to my package since 2021-04-20. What is the status of my package right now? Where is it now? Is it still on its way to Sweden? Postnord Sweden says that it has not arrived in Sweden yet.
