I'd rather have it work like Google Photos does where they are dumped into [year]/[month] folders
Sorting on mobile should work like web or desktop app. The mobile sorts by EXIF Date Taken, and if its not available such as with screenshots it goes by when it was uploaded.
It should instead sort like how the other platforms do, perhaps by date modified?
This is one of the leading reasons I don't use OneDrive for my photos :l
