My tracking info says the same thing:
"A mechanical failure has delayed delivery. We're adjusting plans to deliver your package as quickly as possible. / Your delivery has been rescheduled for the next business day."
What's crazy is that this was posted BEFORE it arrived in Louisville!
My expected delivery date went from 10/23 to 'not available'. I was really hoping to see this having departed Louisville by this morning or at least an update for expected delivery date. Nada! Ugghh....I want my 6 plus!
Whatever it was they fixed it without delay. One of my phones is at the UPS in Lexington waiting for me to pick it up today. The second phone had an original delivery date for tomorrow and it's status just updated as available tomorrow. Ended up not being delayed after all.
