Received an updated delivery from FedEx directly stating it is on time and scheduled for 10/28/23...a full two days from the original and 4 days earlier than the updated date.
Happy, happy, happy!
UPDATE #2: While FedEx states that my delivery date is still scheduled for 10/28/23 I received another update from OnePLus giving me a delivery date of 10/27/23....
However, I do not know from where OnePlus is getting their information? So it may come tomorrow, or the next day, or the next, or......?????
