If you're missing photos after joining an iCloud Shared Photo Library

If you've moved photos to a Shared Library, you won't be able to see those photos on an iPhone or iPod touch with iOS 16 or earlier, an iPad with iPadOS 15 or earlier, a Mac with macOS Monterey or earlier, an Apple TV with tvOS 15 or earlier, or a PC with iCloud for Windows 13 or earlier.

iCloud Shared Photo Library is only available on an iPhone with iOS 16.1 or later, an iPad with iPadOS 16.1 or later, a Mac with macOS Ventura 13 or later, an Apple TV with tvOS 16 or later, or a PC with iCloud for Windows 14 or later. If you open the Photos app on a device that hasn't been updated to a supported version, you won't see the photos that you've moved from your Personal Library to your Shared Library. Find out more about iCloud Shared Photo Library.

To see your photos, use a device updated to a supported version of iOS, iPadOS, macOS, tvOS or from any device with any software version on iCloud.com.
