My Mac Photos albums and folders syncing to iCloud and showing on iPhone/iPad?

Hi all! On my Mac I’ve organized Photos into Folders and Albums. I recently enabled iCloud Photos and all images have uploaded correctly. On iPhone/iPad (and iCloud.com) I can see the photos sorted by date, but none of my Albums/Folder structure shows up.

What I’ve checked / tried

• These are regular albums (not Smart Albums).
• Created a test album on the Mac (“TEST iCloud”) → it doesn’t appear on iPhone/iPad/iCloud.com.
• The Mac library is the System Photo Library (button is greyed out).
• iCloud Photos / Sync this Mac is ON in Photos settings and in System Settings (same Apple ID on all devices).

Question

How can I get the Albums and Folders from the Mac Photos library to sync/appear on iOS and iCloud.com?

Is there a way to force a metadata reindex/resync or any known limitations (e.g., Shared Library, referenced files, etc.) that could block album syncing?

Any tips or steps to troubleshoot would be much appreciated. Thanks!
