Very frustrated. Cannot get iOS 27 to function. I am missing the "Apple Intelligence & Siri" settings item. It just says "Siri". I've scoured forums and the wider internet with no solution. I've done 2 clean installs, first with restore from iCloud. Then without. I've tried every recommendation on settings to do with Siri, ScreenTime, Region, VPN, Language, Voice, etc. I've checked my phone's serial number to make sure it's not one intended for the China market (it's not), and spent many hours trying to fix this. Finally I got something that said: Your primary Apple Account's background tokens are corrupted on Apple's servers and must be escalated to Apple Engineering. So this is not a problem I can fix myself. My understanding is this is the only way to make contact with Apple engineering and I hope someone sees this and can do whatever needs to be done to fix it on the server side... which I hope will translate to it being fixed on the client side. Please help. Thank you.
