Thank you! I thought I was going crazy thanks to that Messages "feature."

That was actually an issue with iOS 10 as well but only in the quick view, not the full app. There you’d see messages out of order and sometimes duplicated.

In the full app opening and closing the keyboard fixes it. I can’t believe they haven’t fixed it, and actually actively made it worse.

> Timer alert is delayed ~10-20 seconds if you look at the screen as it hits 0

I wonder if that's something to do with timer coalescing. The visual timer ticks down in some "cheap" way, but to actually change the view and make a noise, it has an event set in the OS scheduler—and that event only goes off at some large granularity, to prevent the scheduler from burning energy.

I agree, and I don't need millisecond precision on this, but I think multiple seconds is absurd.

weirdly, i regularly had or witnessed the messages issue in iOS 9 and 10, but haven't seen it once on 11(on a 5S, 6, and 6S+ both sides). That's been fixed for me since 11.0

I wonder why some of these are so ridiculously inconsistent
