iOS 17 update on Sept 18 comes without these features

Apple's iOS 17 update, set for September 18 release, won't include all announced features immediately due to delayed components.

Key features delayed for later versions iOS 17.1 or 17.2 include Journal app and collaborative playlists feature.

Journal app allows iPhone users to capture daily experiences, incorporating photos, music and audio recordings; it also makes tailored suggestions.

The collaborative playlists feature in Apple Music enables multi-user addition, reordering, and deletion of songs in shared playlists.

Another functional enhancement includes AirDrop service, allowing content transfer over internet when logged into iCloud, not restricted to physical proximity.

Additional delayed iOS 17 features include varied enhancements to Messages app, Music app, Apple Fitness+ and Apple ID sign-in convenience.
