I wish I could talk to a person to see what is going on.
I mailed a letter with an AirTag embedded to my brother in Libby in mid-December, as he is not receiving key pieces of mail.
So far, the letter made its way to Libby, Missoula, Bozeman, Billings, Seattle (1.5 weeks), Libby, Missoula, Bozeman, Billings and now...once again, Seattle.
The letter is clearly addressed to his street mailbox. Somehow, the letter gets to the Libby post office and then heads back out of town.
Help!
