I have Z6 with the updated firmware. I set automatic switch between EVF and monitor. It looks that the eye sensor for the EVF is too sensitive. From time to time the automatic switching stops working and EVF gets stuck being active. The monitor stays off as if I keep looking through EVF, even when I’m trying to replay photos on the monitor. The only way to (temporarily) fix it is to remove the EVF eyepiece and wipe it and the sensor. After cleaning the switching between EVF and monitor works, but after some time is off again. If I set the mode to monitor only it works, but I really prefer the automatic switching.
