Free 1 year Apple TV+ when you buy an Apple Device
On the 16th Oct 2020 I bought a new iPad Air 4 and I'd heard that you get TV+ free for 12 months when you buy a new device.
I've just seen the 'offer' but when I go to 'Check Availability' it wants me to sign up to the free 7 day trial and then £4.99 a month. How do I get the offer?
Many thanks
