Noticed this recently, past week and a half when I couldn't find recent photos I took. I have one (just one) collection that is out of order on my iPhone (and Mac). It is showing as the latest Collection (newest, at the bottom of the list when viewing collections), instead of my latest photos. All new photos are before this collection.
You have Photos -> Moments -> Collections -> Years
However, in Moments and Years, the photos in said collection are correctly organized by date. No issue. I have not changed anything. I use iCloud photo library. I don't sync to my computer/iTunes. I have changed nothing. I asked a friend if they were familiar with the issue and they were not. However, they looked at their photos and noticed the same issue. Some of their collections were out of order (collections with older dates were after collections with newer dates).
My only conclusion is it was something with the latest iOS update.
Can anyone else confirm they are having this issue? What iOS version you're on, when you noticed the issue?
This was never an issue for me and as of now, there is no way to resolve it.
