Lost my preorder, wouldn’t accept my Apple password, decided it didn’t like my phone number (unchanged in more than 10 years) so eventually resorted to using my Mac rather than the store app on my phone or iPad (even then it took about 3 attempts to sign on and then kept on being diverted to the US site). Finally got through the process at about 1.25pm and thankfully the one I wanted was still in stock for launch day. By far and away the worst pre-order day experience ever. It’s not like this is a new thing as have been preordering since the iPhone 5 came out.
