I tested using a tripod (IBIS off) at MFD as well as several other longer distances at 200mm F2.8 and all were slightly out of focus. When I did the test using manual focus all were in focus. I also tested my RF 24-70 and it was spot on so it’s not a camera issue.

Sounds like you got a lemon. Return it or send it in for repair. This isn't firmware related.

Do you have a RF 70-200 with newer firmware that you’ve tested yourself to know it’s not firmware related? In reading past posts on the subject I didn’t see any that said they updated the firmware and they no longer had a front focus issue.

I do. It's currently at Canon CPS to fix an IS issue or might be slightly decentered. But the focus has always been spot on. You just haven't read far enough – people with the issue report it's gone. It was only an issue at MFD – if yours is not in focus at distance, too, its obviously not the same issue. You'd have RF 70-200 users raising holy hell if every shot was slightly out of focus. I'm done with this thread – you can hold on to your defective lens and wait for a firmware update that will never come, or you can return it or send it for repair. Your choice!
