Nope. Just got back from an African safari. Had both the R1 and two R5IIs running the latest FW. No issues.

There have been some reports of freeze ups after updating on some of the FB R5 mkII forums. May be user error, but I'll wait a while.
Anyone here have any issues? Any AF changes (stills)?

Yea people are saying to turn lens IS off and leave the in body on standard and I’ll be good to go.
You might want to check if that's possible with your lens. I no longer own the 24-70 2.8L (traded it in when I went to prime VCMs) but I just attached my 70-200 2.8L Z lens. If you have the IS switch on the lens to ON, the Image Stabilization setting in the R5ii menu is grayed out, saying it's controlled by the lens (meaning both the lens IS and the camera IBIS is meant to work together and they aren't allowing you to defeat the camera IBIS while the lens IS is on).
I then flicked the switch on the lens stabilization to Off and went back into the camera menu. It was still grayed out. I did a test picture and sure enough, both lens IS and IBIS were off because at 200mm the viewfinder showed shake.
I even turned off the camera and removed the battery for 5 seconds just to see if this was a glitch. Nope. It was still grayed out.
So at least for the 70-200 Z lens, it seems to be a "both or nothing" situation, I can either have lens IS+IBIS on, or both off, but not one or the other.

For bird photography, and since I don’t really shoot video, the main feature I’d be excited about is being able to assign a custom button to toggle pre capture on and off. Honestly, that’s something I’ve been wishing they’d add for a long time
