Apple Software Update Bug Re-Enables Disabled AI Features

A bug in iOS 18.3.1 and macOS 15.3.1 updates has caused Apple Intelligence to reactivate on some devices, frustrating users who had previously opted out.

The latest iOS 18.3.1 and macOS 15.3.1 updates have reportedly re-enabled Apple Intelligence on certain devices without user consent.
The issue appears linked to devices displaying a Welcome screen post-update, which sometimes forces the AI feature to activate automatically.
Users who had previously disabled Apple Intelligence have expressed frustration over the need to manually turn it off again.
The bug seems inconsistent across devices, with some iPhones, iPads, and Macs unaffected, while others reactivated the feature unexpectedly.
Apple has not yet commented on the issue, but the bug is expected to be addressed in future updates.
