Apple's iCloud service synchronization encountered a failure: iOS 16.3 has multiple bugs!

According to feedback from some iCloud users, after upgrading to the new version of iOS 16.3, they found that applications such as iCloud Drive and Photos could not be synchronized. According to preliminary analysis by foreign technology media AppleInsider, this may be due to the lack of two-factor authentication.

According to user feedback on Apple’s official support forum and Reddit community, some users have encountered iCloud synchronization problems after upgrading to iOS 16.3. The main symptom is that the iCloud Drive and iCloud Backup services have an error message during the synchronization process: "An unexpected error occurred. Please try again later." This problem has caused concern and trouble among users.

Apple’s latest operating system, iOS 16.3, introduces a new Apple ID security key feature. According to Apple, this optional security feature is designed for individuals who want additional protection in the face of targeted attacks such as phishing or social scams.

After logging in to Apple ID, you need to enter the user’s account password. For added security, two-factor authentication is now completed using a FIDO-certified security key instead of the traditional six-digit verification code, which often comes from another Apple device.

Based on the latest feedback, most users experiencing sync failures did not have two-factor authentication enabled. Further reports suggest that enabling two-factor authentication may be a solution to this problem, but not everyone wants to enable this security feature on their accounts.

Introducing a powerful iOS device data backup, transfer and management tool - Apple Data Management Tool. This tool supports backing up data on iPhone/iPad devices and can selectively back up data. Users can freely choose to back up videos, music, contacts, text messages, applications and other data to the computer. Using this tool, users can easily manage and transfer data on their devices, ensuring data security and reliability. Whether it is backing up important data or migrating data to a new device, this tool can meet the needs of users.
