Managed to get confirmation email come through at 13:00, so must have been on it like sonic!
I did have a minor fright, as I got an email - "Your invoice from Apple" - at 12:58 whilst I was opening/closing/opening the Store App, but it was for my rolling monthly Apple Music subscription! 😱😂 Terrible timing!
I will need to change the delivery address (changed it on the App store, but seemingly not Apple Pay...) as I'm not at my regular address for Lockdown 2.0, but wanted to get an order in asap and will get onto Apple Live Chat later.
Hope you all got into the site ok and got what you wanted.
