I just shot an email to UPS Customer Support, waiting for an answer in an hour max.
But my MyUPS account says delivery will really happen tomorrow…
I can't figure out how the hell the package is supposed to make the trip from South Korea to an airport in Europe, then go through sorting in a facility and then get delivered on Wednesday… That'd be extremely fast, they have less than 24h
The only way I see it is tracking being unsynced. It happened before for me with a few packages.
The tracking finally caught up only when the driver came to my door
