With a buffer period, Apple does not support the recent addition of iCloud advanced data protection features.

CTOnews.com, December 10 (Xinhua)-- by upgrading to iOS 16.2, iPadOS 16.2 and macOS 13.1 (expected to be released next week), Apple users are expected to enable iCloud's Advanced data Protection (Advanced Data Protection) features and enable Photos, Notes, Reminders, Voice Memos and other services to enable end-to-end encryption.

In order to better protect users, new devices under Apple's Apple ID account need a certain buffer period to enable Advanced Data Protection. According to some user screenshots, this feature will not take effect until the end of January or early February.

CTOnews.com learned that he wrote in the reminder:

Since you recently added this device, you will not be able to enable Advanced Data Protection until February 2, 2023. We will help protect your account and data during this waiting period.

The old devices that have been added under the Apple ID account can enable the Advanced Data Protection function normally. In this case, all devices added to the Apple ID account are fully protected by end-to-end encryption of the iCloud extension, including newer devices that are still waiting.
