R3 in Cold Weather

I am comparing the specs on Canon R3 and Nikon Z9 on B&H. Under temperature performance (in Farenheit), the Nikon is rated down to 14 degrees but the Canon is only rated to 32 degrees (freezing). Surely this can't be right, that a gripped pro body will not work below freezing? Has anyone used an R3 in low temperatures and able to give a report?

This is likely stating the obvious: Keep in mind that the current batteries need to have their dielectric fluid be, well, fluid to function. So regardless of body specs, batteries will always be a weak point at lower temperatures.
Always best, to keep a spare battery close to the body.
I've worked with my 5D4 and LP-E6 (old) at least 1 hour at -18°C (0°F) before Christmas.
The spare battery stayed in the pocket. But the drain was much faster because of the low temps.
