Thanks for the feedback everyone. I've updated my R5II, and everything seems fine so far.

Hows autofocus? 1.0.3 regressed AF accuracy. Curious if they resolved.
I never installed 1.0.3. I haven’t done enough shooting yet to tell whether there’s any difference from 1.0.2 in that regard.
When I first installed v1.0.3 I noticed AF issues. So the first thing I did was reinstall 1.0.3 over itself and now the AF is back to being awesome (I shot an airshow last week and was absolutely flabbergasted).

Wait a minute. You reinstalled 1.0.3 over itself? Not 1.0.2 over 1.0.3? So your R5II went from having 1.0.3 to 1.0.3 (?!). And that changed things? How would that work? Any idea?
Indeed. There have always been reports of firmware updates just not "taking" well (causing irregularities for some users). I've experienced it myself a couple of times. This time instead of rolling it back a notch, I just reinstalled it over itself to see if that would clear things up. Fortunately it did!
I can't be 100% sure of the cause and effect, because at the same time of the reinstall, I also lengthened the "sleep" timers (as suggested by some folks online). But after shooting some 30,000 pics since then, I've been absolutely gobsmacked by the R5ii's performance. I'd recommend anyone who has had issues after an update do the same, at least for starters.
