I had ISO on the bar and still do, the problem was that the lock was off so every time my thumb touched the bar while shooting it changed the settings to the upper side. I was in full sunlight shooting at high ISO's which obviously is less than ideal. The good news is that the camera handles those higher ISO's better than I thought it would.

I put the lock back on which pretty much requires that you take a secondary action to activate the bar. I have still not yet decided how to assign all the buttons, I had really gone out to evaluate the tracking on that camera but had unfortunately left the EF adapter at home so the only lens I could shoot with was the FD lens. I am not so thrilled with the missing command dial on the back of the camera that has been replaced but the Touch Bar, I think that Canon was trying to put a really digitally advanced camera onto the market and I am not so sure that it is anymore functional than the older simpler designs. The camera has some pretty advanced shooting and review menus that I guess if fully used could become invaluable but this camera is going to require some getting used to.

If it will track I will get rid of my IV but I am not so sure about the tracking as I have read some negative things about this camera's ability to track. There is a lag in the EVF after releasing the shutter I was able to see that yesterday with the vintage lens, but I don't know how badly that will effect tracking a bird in flight, the focus system itself is supposed to be better than the 5DIV but I have heard the same feedback you have on tracking.

Had real problems first day out with my new Canon R and an old vintage lens. The touch controls really made a mess of things, I think that Canon went a bit far with their Touch Bar, but like I said, it was my first outing, I am sure that things will get better with becoming more familiar with the camera. Needless to say you might imagine my surprise after taking 50 to 100 images noticing on review that the ISO setting was 128000, I had definitely set it below 400 before leaving the house.

Anyway, the reason I was happy to get the R was that I will from time to time shoot with old vintage lenses, all the images below were shot with an old Canon FD 300mm f/4.
