So, who else recently got offered an iOS 18 update on their iPhone that was already running iOS 18? I did, and I installed the update, after which I saw the “Hello" welcome screen again and then got prompted to enable Stolen Device Protection. Weird.

(And, no, I never ran any of the iOS 18 betas.)

@siracusa there’s a supplemental update for 16’s, you wouldn’t be prompted to update during setup, but rather after transfer is complete.
