Anyone in the US buy a RF 70-200 2.8 IS recently?

what do you mean by intermittent AF issues? and how can you tell how old the lens is by the serial?

It misses the focus in instances when it shouldn't, and it's happened multiple times (i.e. non-challenging scenarios where my 1D4/5D4 and EF 70-200 2.8 IS II always hit). But I haven't used the RF (nor the R5) enough to rule out anything yet, which is why I just want to determine if the lens I got was possibly flawed/a return. If a few other people recently got RF 70-200s that were produced last year, that would ease my mind a bit

The R5 does not have any cross type AF points so there are some scenarios where the R5 will not find focus that the DSLRs would. Could it be that these situations only have contrast in one direction?

Thanks for the suggestion, but there's good contrast in both directions, so I don't think that's it. Like I said, I need to do more testing to rule some things out, but I'm hoping someone will chime in about the serial numbers. But I may be exchanging the lens anyway, since it came with a fairly big piece of dust or some other debris speck inside as soon as I pulled it out of the box (part of the reason it feels like a return...with the other being the old production date).

Mine was purchased in January, and has a date code that looks like October, 2019.  I have had no issues with mine focusing.
