Apple Intelligence is stuck on "PREPARING" on my iPhone 16
I recently updated to the latest 18.1 Official Release and applied for Apple Intelligence on October 28, 2024. I set my region to the United States and the language to English (United States). At first, it got stuck on "PREPARING." When the status didn't change, I tried some tips from other iOS 18.1 users, like switching between regions and languages. That helped me enable the Apple Intelligence toggle icon, but I still can’t use Apple Intelligence on my iPhone 16. Any ideas on what to do next?
