Photo thumbnails disappeared after iPhone 15 Pro Max upgraded to iOS 17.2 RC

[WolfSnap]

Upgraded my device to 17.2 RC last night, and noticed that about half of the thumbnails for photos in my iCloud library disappeared. Just got white squares instead of the thumbnails that were there before upgrading.

If I try to view the photos, the thumbnail will regenerate and show again. But, I have over 68,000 photos.. Might take a while to scroll through them all.

Any way to repair the library? Force a regeneration? Anyone else have this issue?

Same, in my case I restored my iPhone 15 pro max and MacBook Pro, with the same issue.

I have this issue. Had iPhone 11Pro, 27,000 images stored on Mac desktop, and turned on iCloud Photos - they ALL synced upt to iCloud and then I ennabled iCloud Photos on iPhone11Pro and they ALL synced down to the device, with some 100 albums ALL fully populated with thumbnails.

Repeated this on an iPad pro, and ditto.

Bought iPhone 15 Pro and once set up, the bottom line is that any album with over approx. 30 photos has blank thumbnails with cloud symbol. If I manually scroll through the ENTIRE album they load, and fairly quickly if I'm on decent wifi.

However, if I do not manually enter and scroll every single photo, or leave the scroll process before they've all synced/downloaded, I have blanks.

Like the OP, I have a lot of photos to sit there and sync manually!

Apple say it's 'expected behaviour for a new device' but that's rubbish. Especially after two weeks and >500Mbps internet.
