Once you install the new firmware - is it possible to go back?

As far as I know, there is no way to go back.

You can infact go back. Download the previous firmware from Canon's site and then use the EOS Utility to revert. Did it yesterday going back to 1.4.0 on my R6. It was super duper easy. Once you camera is connected to the EOS Utility click on "Settings" then "Firmware Update" and follow the prompts. It will say that you have the latest firmware but just click on "next" and it will eventually take you to a screen where you can select the firmware from your computer. You select the old firmware and then it shows you on your camera screen that you are reverting to a previous version. See below for screen shots of the process.

firmware 1.5 is still on canon usa site... are there actual issues? I did notice it hunt more than before, but also having issues with the lens I was trying it on.. so wasn't sure if it was firmware or lens.

I downloaded the new firmware but have been too busy to bother installing it. I guess I'll wait another week and see.

This is true...all three are missing off the UK site (R5, R6, and 1DX Mark III). Very interesting development indeed...

I have 2 R6's and access to 2 1DXIII's. No problems thus far.
I have just downloaded the R6 update from the UK site and no issues so far ?

It seems people are experiencing more erratic and less stable Eye AF now. I’ll have a go at ice skating today and I’ll try to see if inexperience the same thing.

Canon USA has the same firmware still available. I'm seeing no problems on either R5 or R6.

Any solid evidence of issues?

Thanks for sharing, I tried this , but it only says "failed to transfer firmware" and it doesn't do anything else.

You may have too many versions of firmware on your card, you can try a clean card.

It was formatted before I gave it a try.
Do you have more than one card in the camera? My R5 didn't like having firmware on both the SD and CFe, so I removed the SD card to update to 1.5.0.

I tried the 1.5.0 again today, and now all of a sudden I get the one box over the torso and it’s much better, seems other people also experience this. Works then doesn’t work.

I upgraded two R5s and no issues so far. In fact, it *SEEMS* like eye AF was much improved for me. I had a shoot the day after upgrade and I tested after upgrade with no issues at all. Shoot went perfectly and definitely seemed like eye AF performance and accuracy was improved, idk, maybe it's just placebo, but I had 2 shoots in a row with 1.4.0 where I felt like eye AF was letting me down so I switched it off.
