What it means

UniUni states that if the second delivery attempt fails the parcel is returned to their warehouse, where it is stored for 30 days. It is not simply retried a third time.

Should I worry?

Yes. Two failures ends the delivery attempts — from here it sits in a warehouse on a 30-day clock.
