Connect your device to power
If your device seems to be stuck on a status message that says Syncing [number of items] to iCloud or Syncing with iCloud…, connect your iPhone or iPad to power and to Wi-Fi.

Check which Library view you're in
If you set up iCloud Shared Photo Library in iOS 16.1 or later, iPadOS 16.1 or later, or macOS Ventura or later, check which Library view you're in. When you move photos to your Shared Library, you no longer see them in your Personal Library. You also won't see photos moved to your Shared Library if you're on a device with an earlier version of iOS, iPadOS, or macOS or if the iCloud Shared Photo Library owner has run out of iCloud storage.
