iCloud Photos not in date order
I've just uploaded my wife's 16,000 photos and videos, from the Photos app on her MacBook, to iCloud Photos (it took a long time!).
When we go to icloud.com and look at the photos in the 'Moments' they appear to be in date order. But if we switch to 'Photos' they are not displayed in date order.
I suspect they might be displayed when we imported the photos from her iPhone (via a lightning bolt to USB cable), rather than when the photos were taken. I suspect this, because we'd only import photos once or twice a year, and in iCloud Photos, in 'Photos' (not Moments) the photos seem to be grouped together in big monthly groups, i.e. all photos in 2021 appear under December 2021.
How do we get the photos to display in date order of when they were taken, not when they were uploaded from the iPhone to the MacBook? And why do they display fine in Moments?
