I registered with UPS My Choice (App) this morning based on what other people in this group said. I filled in my address, email, phone etc and although it was previously blank, the delivery has now shown up.
I’m in the UK and my watch is coming from China. It says delivery will be on the 22nd, which is Tuesday. Apple had said it was the 28th, so as I mentioned before, under promise and over deliver.
My order has now updated on the Apple app, with a link through to UPS tracking (screenshot also attached). Apple still say it’s coming on the 28th but all tracking points to the 22nd.
