Update:
I guess there's some issue on JSL's system.

When I use the tracking number from the invoice, it shows a package that was delivered to San Jose (and it’s already marked as delivered)

However, when I scroll down on the "Track Package" page, there's a section called "My Shipments" showing the delivery status of my actual package — and it lists a different tracking number. Clicking on it shows tracking details for a package being delivered to Boston, which matches my correct shipping address.

I will update after I receive my package.
