Apparently its been fixed with "Nov 19 changes"
After changes to the Defibrillators in Update 1.1.2.0 made them more demanding in terms of accuracy and target range, we've published a backend update to bring their usability back in line with our original intentions. We've increased their effective hit-boxes and range, which should make Defibrillators feel more consistent with previous gameplay.
Same thing today also. Defibs just don't work anymore. You need to drag revive people.
I worked perfectly before the update and now there's little hope of rezzing people up anymore
