iPhone Camera Roll recents no longer recent.

I'm curious why, when I try to add photos on LR Mobile, the photos are now ordered by date taken as opposed to most recently added?

Previously I was able to, say, export a watermarked .jpg to my camera roll and then re-add it to an album where it'd be the first photo available in "Recents." 

Now, and especially as the date taken length increases, that same exported .jpg is no longer the first photo availabile in "Recents," it is buried a mile's scroll away from the top. 

This has changed and wasn't always like that. Is there a particular reason this was changed and if not and it's a bug, can it please be addressed? I do the bulk of my work on my phone and this is messing up my workflow for no apparent benefit.
