iMessage displaying conversation threads out of order on iPhone

I've been having some big issues with my iPhone lately, but the most infuriating one by far is that my messages are not displayed in chronological order. The usual way is that a new message from a contact brings that thread to the top of the list, but about two weeks ago, my threads got sorted into a completely random order and, worse, when I get a new message, that thread isn't bumped to the top anymore.

So, when I get a new message, I have to scroll quite a ways to even find it. I've tried updating iOS on my phone. I've restarted my phone, turned off iMessage then back on, deactivated iMessage on my Macbook and reactivated just to see, and nothing's worked. Anyone have any ideas what the heck is going on here? This is on an iPhone 6 with iOS 10.3.2.

Solution 1:

My children sometimes change the date / time on my phone so that they can trick certain games that they play on it. Then, my messages no longer sort correctly. I just fixed my phone by setting the date and time to update automatically.
