Updating to the latest iOS, which included a critical security patch, once again enabled my Apple Intelligence. This happened with the last update, someone reported it on HN so I thought to check. Once again, there it was enabled.
Looks like this was previous reported. Only seems to affect some users.<p><a href="https://www.macrumors.com/2025/03/11/ios-18-3-2-apple-intelligence-auto-on/" rel="nofollow">https://www.macrumors.com/2025/03/11/ios-18-3-2-apple-intell...</a>
Updated iPhone and two iPads yesterday. None of them had Apple Intelligence turned on after the update completed. Maybe it happens to some people but I doubt Apple deliberately re-enabled it in the update.
