Any A7R iv A issues with 200-600 zoom?

[Tampa]

I’ve read tons of older posts about what sound like serious focus issues with the A7R IV and the Sony 200-600 zoom.

I’m on the verge of buying that combination (actually the A7R IV A) but I’m wondering whether the issue has been resolved, and can’t seem to find anything definitive. I’d be  buying new, not used equipment, but obviously I don’t want to step into a problem.
Anyone have any info on that?

I've been using the 200-600mm zoom with my ILCE-7RM4A for several months for birding and don't appear to have the focusing issue. I would recommend this setup

There was a problem with the A7RIV and the 200-600. However, it was eventually isolated to a particular non-default setting. I do not remember what the setting was, but you should be able to find it. 

I do not know if the A7RIVA has the same problem.

Here's a good thread on the issue....

And here is the info on the A7RIVA that maybe explains why I don't see the issue... 

The change in wording that caught my attention is that the new A7RIVA brochure says the structure has been "re-examined and redesigned." Don't know, but given the text of other parts of the brochures are copied word for word, the change in text here seems significant. My reading of this is that it is a redesign of the A7RIV. In that case, perhaps the 200-600 issues are less severe with the new body.
