Can't delete hidden videos in iCloud

Hi tanphan6061,

Thanks for using Apple Support Communities. We understand you have some questions about deleting videos from iCloud. It looks like those videos didn't load, but you can still try selecting them to delete using the steps here:

1. In Photos on iCloud.com, select the photos or videos you want to delete, or double-click a single photo or video.

2. Click , then click Delete.

3. Deleted photos and videos are moved to the Recently Deleted album.

4. To permanently delete photos or videos before they’re automatically deleted, go to the Recently Deleted album, select the items you want to delete, then click Delete [number] Items.

See more about that here: Delete and recover photos and videos on iCloud.com - Apple Support

Thanks.
