I have the Yongnuo 685 Flash, and also the Transceiver ... and have used it on my d850. I did not have to set anything special on the D850, just made sure the channels were the same on the 685 and the 622 Transceiver and the that 685 was set at 622R.Slave. I mixed a little bit of help from the manual, with some experimentation to get it to work. Once you have those settings, hold the test button down for about 5 seconds, then release. When all is set right, the flash will fire.
You have committed a sin. How dare you put a Yongnuo flash on a new $3300 D850. Just kidding. I happen to own a Yongnuo too. But, I have mine on a DX camera. Actually, the Yongnuo #685 has been compared to Nikon's SB-910.
